Best Answer

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.

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.

To find the roots (solutions) of a quadratic equation.

I suggest you use 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

A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.

To find the roots (solutions) of a quadratic equation.

When an equation cannot be solved for "x" to find the zeroes, the quadratic formula can be used instead for the same purpose.

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.

I suggest you use the quadratic formula.

the formula you are going to use to answer the equation

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.

To find the solutions of x in a quadratic equation.

A quadratic equation.

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.

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

The quadratic formula is used to find the solutions (roots) of a quadratic equation in the form ax² + bx + c = 0, where "a," "b," and "c" are constants.
