How do you find the answer to a quadratic equation from the quadratic formula?
Answerman1621
Plug 'a', 'b', and 'c' from the equation into the formula.
When you do that, the formula becomes a pair of numbers ... one number when you
pick the 'plus' sign, and another number when you pick the 'minus' sign.
Those two numbers are the 'solutions' to the quadratic equation you started with.

What is the difference between quadratic formula and quadratic equation?
There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.
Why do mathmaticians use the quadratic formula?
To find the roots (solutions) of a quadratic equation.
How can you find the complex solutions of any quadratic equation?
I suggest you use the quadratic formula.
Solve this quadratic equation using the quadratic formula?
For any quadratic ax2 + bx + c = 0 we can find x by using the quadratic formulae: the quadratic formula is... [-b +- sqrt(b2 - 4(a)(c)) ] / 2a
What is equadtratic equation?
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.

Why do mathmaticians use the quadratic formula?
To find the roots (solutions) of a quadratic equation.
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 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.
How can you find the complex solutions of any quadratic equation?
I suggest you use the quadratic formula.
What must be true of an equation before you can use the quadratic formula to find the solutions?
the formula you are going to use to answer the equation
What is the quadriatic formula used for?
To find the solutions of x in a quadratic equation.
What statement must be true of an equation before you can use the quadratic formula to find the solutions?
The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.
What is an equation that can be used in quadratic formula completing the square and factoring?
A quadratic equation.
Can the answer to a quadratic equation be a decimal?
Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
Solve this quadratic equation using the quadratic formula?
For any quadratic ax2 + bx + c = 0 we can find x by using the quadratic formulae: the quadratic formula is... [-b +- sqrt(b2 - 4(a)(c)) ] / 2a
What formula name that gives the solutions for x in a quadratic equation?
This formula is called the quadratic formula.
