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.

The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.

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.

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.

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

you use the quadratic formula in math when the quadratic equation you are solving cannot be factored.

Using the quadratic equation formula is a method of solving quadratic equations.

Simply learn and use the quadratic equation formula.

By using the quadratic equation formula or by completing the square

The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.

This formula is called the quadratic formula.

The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?

By knowing how to use the quadratic equation formula.

Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.

It is a quadratic equation and its solutions can be found by using the quadratic equation formula.

Well, if the given quadratic equation cannot be factored, nor completed by the square, try using the quadratic formula.

If the discriminant of b2-4ac in the quadratic equation formula is less than zero then the equation will have no real roots.

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

The discriminant

The Quadratic Equation is useful because you can't factorevery equation, so you use the quadratic equation. Even though it doesn't seem fun it is still useful.

a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.

You convert the equation to the form: ax2 + bx + c = 0, replace the numeric values (a, b, c) in the quadratic formula, and calculate.

Using the quadratic formula to solve any quadratic equation is the best way of getting around it because the quadratic formula is "the opposite of b plus or minus the square root of b squared minus 4ac all divided by 2a. This formula only works with trinomials and second degree equaitons. If the equation is a binomial, then put in a placeholer (0) and substitute them into the equation.
