It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.

In factoring a quadratic equation involving some X 's and a plain number you see that the sign in front of the X is negative and the sign in front of the plain number is positive?
That means that both of your brackets will have minus signs.
What is 2x squared minus 3x minus 4 in factored form?
If that were x^2 - 3x - 4, it would be (x + 1)(x - 4) As it is, it doesn't factor neatly. Applying the quadratic formula, we find two real solutions. (3 plus or minus the square root of 41) divided by two. x = 2.350781059358212 x = -0.8507810593582121
What does M mean on a calculator?
Memory. It's the button that saves your current number, and when you press MRC, or Memory ReCall, the number is restored, giving you a great way to add two products if you have a basic calculator, or to do otherwise impossible equations that have many separate parts.
Does it matter what two factors you complete to a factor tree?
In doing the factor tree, you can start with any two factors of the given number. These factors maybe prime or composite. But the resulting factors in the factor tree should always be prime numbers. It means that you have to continue factoring unless you ended up with all prime factors.
What does it mean to factor?
In mat, to factor something means to make the greatest common factor distribute to the rest. (This is hard >.<). Basically factoring means to turn that expression in a distributive expression. For example: The question tells you to factor 93+36 So you find the greatest common factor, which is 3 You put 3 as the number distributing the number 93/3=31 36/3=12 The quotient become the numbers you put in your parentheses So the final answer will be like this : 3(31+12) Sorry Its hard explaining math :P
Can all quadratic equations be solved?
Well, that depends on what you mean "solve by factoring." For any quadratic equation, it is possible to factor the quadratic, and then the roots can be recovered from the factors. So in the very weak sense that every quadratic can be solved by a method that involves getting the factors and recovering the roots from them, all quadratic equations can be solved by factoring. However, in most cases, the only way of factoring the quadratic in the first place is to first find out what its roots are, and then use the roots to factor the quadratic (any quadratic polynomial can be factored as k(x - r)(x - s), where k is the leading coefficient of the polynomial and r and s are its two roots), in which case trying to recover the roots from the factors is redundant (since you had to know what the roots were to get the factors in the first place). So to really count as solving by factoring, it makes sense to require that the solution method obtains the factors by means that _don't_ require already knowing the roots of the polynomial. And in this sense, most quadratic equations are not solvable through factoring.
Why are there usually two solutions to a quadratic equation?
In the graph of a quadratic equation, the plotted points form a parabola. This parabola usually intersects the X axis at two different points. Those two points are also the two solutions for the quadratic equation. Alternatively: Quadratic equations are formed by multiplying two linear equations together. Each of the linear equations has one solution - multiplying two together means that the solution for either is also a solution for the quadratic equation - hence you get two possible solutions for the quadratic unless both linear equations have exactly the same solution. Example: Two linear equations : x - a = 0 x - b = 0 Multiplied together: (x - a) ( x - b ) = 0 Either a or b is a solution to this quadratic equation. Hence most often you have two solutions but never more than two and always at least one solution.

When factoring a trinomial that is in the format ax2 plus bx plus c?
Use the quadratic equation: x = [-b +- sqrt(b^2-4ac)]/2a The +- means you get two answers, one by adding, one by subtracting.
How do you simplify math?
You can't. Math is not an algebraic expression. Simplifying an equation, however, can take multiple forms. Sometimes simplify simply means to solve an equation. Other times, it can mean to bring an equation into a standard form, such as with line equations, or quadratic equations.
Why did al-khwarizmi invented algebra?
Al-Khwariami invented al-jabr as a means of solving linear and quadratic equations. This was done by reducing the equation to one of six standard forms.
Is A quadratic polynomial has a degree greater than 2?
No. "Quadratic" means degree of 2.
How do you solve S squared plus 4s minus 21 equals to 0?
To solve the quadratic equation, S^2 + 4S - 21 = 0, you can factor the expression or use the quadratic formula. Factoring, we can rewrite it as (S-3)(S+7) = 0. This means that either S-3 = 0 or S+7 = 0. Solving for S in each case gives S = 3 or S = -7 as the solutions to the equation.
What exactly is a Factoring Company in Omaha, Nebraska And what exactly do they factor?
not only in Omaha but any where factoring company means a finance company. They provide financial assistance
What does it mean if the roots of a quadratic equation are real?
It means that they can be represented by real numbers or lengths along the number line. It means that the graph of the quadratic crosses (meets) the horizontal axis.
How do you translate Quadratic equation?
Translate to what? I assume you need help interpreting it. The quadratic equation is used to solve the quadratic polynomial, ax2 + bx + c = 0, where a, b, and c can be any number. For example, if you need to solve the equation x2 = 5 + 2x, you first convert it into the standard form mentioned above: x2 - 2x - 5 = 0. Now find the coefficients, a, b, and c. In this case, a = 1, b = -2, c = -5. Finally, you replace these coefficients in the quadratic equation. The "plus-minus" sign simply means that the quadratic equation is a shortcut for two equations - one in which you add, the other in which you subtract, the terms at the top. The solutions given by the quadratic equation are values of "x" that satisfy the equation.
What does solving a system of equations actually mean?
That means to find values for all the variables involved, so that they satisfy ALL the equations in a system (= set) of equations.That means to find values for all the variables involved, so that they satisfy ALL the equations in a system (= set) of equations.That means to find values for all the variables involved, so that they satisfy ALL the equations in a system (= set) of equations.That means to find values for all the variables involved, so that they satisfy ALL the equations in a system (= set) of equations.
