You need to put your equation in this form...
ax2 + bx + c = 0
Then identify your a,b and c

Can the problem of computing the number pi be solve exactly?
no. technically and scientifically speaking, there is NO such thing as EXACT distance, time, or measurement (height, length, width, weight, speed).
How do you tell your mom your ready for bras?
The easiest thing to do is just tell her. You can start by asking her when she first started to wear a bra, or let her know that you're uncomfortable sometimes.
How do you write a mixed number or fraction as a percent?
For a fraction, divide the numerator by the denominator and multiply by 100 for a percentage. If it's a mixed number, you first have to convert it to an improper fraction then do the same thing as for a fraction.
1 is what?
depends on what you mean by the question. it is a whole next to 0, it is the easiest thing to multiply by it is the first ordinal number it is an Arabic numeral it is the first of the natural numbers it is the second of the base ten numbers it is the integral ( -infinity to infinity) of f(t)\ dt in real numbers it the infinitely recurring decimals 0.99999999... and 1.000000... .
What is 30 percent of 1206 dollars?
The first thing to note is that a percent is that number over 100. So 30% is 30/100. The next thing to know is that "of" in mathematics means multiplied by. For example 2 lots of 8 is 2x8. In this case, the question can be rewritten as 30/100 x 1206. This comes out at 361.8 Thus, 30% of 1206 dollars is $361.80
Advantages and disadvantages of using journals in mathematics?
Somebody (possibly in seventh-century India) was solving a lot of quadratic equations by completing the square. At some point, he noticed that he was always doing the exact same steps in the exact same order for every equation. Taking advantage of the one of the great powers and benefits of algebra (namely, the ability to deal with abstractions, rather than having to muck about with the numbers every single time), he made a formula out of what he'd been doing:The Quadratic Formula: For ax2 + bx + c = 0, the value of x is given byThe nice thing about the Quadratic Formula is that the Quadratic Formula always works. There are some quadratics (most of them, actually) that you can't solve by factoring. But the Quadratic Formula will always spit out an answer, whether the quadratic was factorable or not.I have a lesson on the Quadratic Formula, which gives examples and shows the connection between the discriminant (the stuff inside the square root), the number and type of solutions of the quadratic equation, and the graph of the related parabola. So I'll just do one example here. If you need further instruction, study the lesson at the above hyperlink.Let's try that last problem from the previous section again, but this time we'll use the Quadratic Formula:Use the Quadratic Formula to solve x2 - 4x - 8 = 0.Looking at the coefficients, I see that a = 1, b = -4, and c = -8. I'll plug them into the Formula, and simplify. I should get the same answer as before:
What are the pros and cons of solving quadratics by using the quadratic formula?
One pro of using the quadratic formula is that it will produce complex (imaginary) roots just as easily as it can produce real roots. (Factoring with imaginary numbers is a kind of a nightmare!) Another pro to the quadratic formula is that it eliminates the frustrating guess-and-check process. A con of the quadratic formula is that, when it comes to more simple problems, it is usually more time-consuming. A lot of textbook problems are quite easy to factor in your head--it is often not worth the effort of plugging numbers into a long formula. A second con of the quadratic formula is that it is quite long--you might write out the formula, accidentally forget a letter, and whole thing is useless. It's much easier to see that your work is correct when you're factoring.
Do you have to pass math in six grade?
The only thing that you really need to know is the quadratic formula, its uses in everyday life. that's all
How do you solve x2 - 4x 41?
Equations have solutions. I'll assume that's x^2 - 4x + 41 = 0 since this website can't reproduce plus or equals signs in questions. That doesn't factor neatly. Using the quadratic formula, we find two imaginary solutions: 2 plus or minus i times the square root of 37x = 8.082762530298219ix = -4.082762530298219iwhere i is the imaginary square root of -1no its is x^2-4x=41
Explain a Quadratic equation and how to solve it?
A quadratic equation is any equation that can be expressed as ax2 + bx + c = 0.Note that the a, b and c are specified, x is the only unknown.Example:x2 - 10x - 24 = 0a, b, c are the coefficients of each term.Now x2 appears not to have a coefficient, but remember x2 is the same thing as 1x2 so the coefficient is 1. So a = 1.The second term has a coefficient of -10 because it has a minus, not plus sign in front of it so b = -10.Likewise for c, the third term. C = -24.So you have your terms.There are two popular ways of solving this.You can factorise the equation, or use the Quadratic Formula.I prefer to use the Quadratic Formula, as it is very straightforward, you just need to practise it.The quadratic formula is x = (-b±√(b2-4ac))/2a
What is the thing typed in the active cell to start a formula?
The first character in a cell to indicate a formula is the equal sign (=).
How do you solve a problem with area of baseheight?
There's no such thing as "area of baseheight". Those are some words you overheard when the rest of the class was actually learning a formula for something, possibly the area of a triangle or a parallelogram, or even the volume of a cone or cylinder. Your best move is to go back and learn that formula. After that, the way to solve a problem where that formula is the appropriate one is to use it.
Is -2x squared plus 2x plus 1 equals 9 a quadratic equation?
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
When the problem is in parenthesis do you use the order of operations to find a solution?
Yes, and parenthesis are the first thing you solve.
What type of entry does Excel assume you are typing if the first thing you type in a cell is a equals?
A formula.
How do you finish episode 42 on Pocket God?
I know how to solve the first clue. Go to where the jellyfish are. The Pyramid looking thing in the water. Then click on the symbols on the pyramid thing. I dot know how to solve the next one. It's something like felling blue
What is the first thing to do to solve a math problem?
You should read the problem and any directions, graphs, charts, and data that goes with the problem
