What does it mean in algebra to complete the square?
A quadratic equation can be solved by completing the square which gives more information about the properties of the parabola than with the quadratic equation formula.
Can anyone help with this problem solve Quadratic problem 3x2 4X -2 0?
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
Are quadratic functions symmetric with respect to the y-axis?
No, but they are symmetric with respect to a line parallel to the y-axis - which could be the y-axis itself.
Can quadratic systems be solved using elimination and substitution?
You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.
What is 2xSquared-2xy?
4
What part of the a quadratic formula tells you when the quadratic equation can be solved by factoring?
The discriminant
What is 3x2 plus 18x plus 15?
It is a quadratic expression in x, which is equivalent to 3*(x+1)*(x+5). Since it is not an equation it cannot be solved.
What is the quadratic formula for?
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
What is 6x2 plus 20xy plus -16y2?
It is a quadratic expression in x and y. Since it is not an equation it cannot be solved or represent any shape in the 2-dimensional plane.
What is equadtratic equation?
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.
A square b square -2ab - 25?
a2b2 - 2ab - 25 is a quadratic expression in the variables ab. There is no equation or inequality in the question so there is nothing that can be solved. Because of the nature of the expression a and b cannot be separated in any meaningful way.
What is9x2 plus X plus 49?
It is a quadratic expression in one variable, x (assuming that x and X are the same). Since it is not an equation, it cannot be solved. Also, it has no real factors.
How do you work out 3x squared -10x equals -5?
This is a quadratic expression in x. It cannot be solved because it is an expression: there is no equation to solve. Furthermore, the discriminant for the quadratic = (-10)2 - 4*3*(-5) = 100+60 = 160 which is not a square number. There are, therefore no rational factors. While it would be possible to give irrational factors, factorising a quadratic into linear terms containing irrational numbers is rarely useful.
Can you solve a math expression?
No. An expression cannot be solved.
What does quadratic formula find?
When an equation cannot be solved for "x" to find the zeroes, the quadratic formula can be used instead for the same purpose.
Can Quadratic equations that can be solved using the quadratic formula also be solved by factoring?
Yes, however not all quadratic equations can easily be solved by factoring, sometimes you can factor and sometimes it is easier to use the quadratic formula. Example: x2 + 4x + 4 This can be easily factored to (x + 2)(x +2) Therefore the answer is -2 by setting x +2 = 0 and solving for x This can be done using the quadratic equation and you would get the same results, however, it was much faster to factor instead.
