Top Answer

The quadratic equation in standard form is: ax2 + bx + c = 0.

The solution is x = [-b ± √b2- 4ac)] ÷ 2a

You can use either plus or minus - a quadratic equation may have two solutions.

0The 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.

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.

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.

This formula is called the quadratic formula.

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

By using the quadratic equation formula or by completing the square

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

By knowing how to use the quadratic equation formula.

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

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

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

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

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

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

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.

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.

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

I suggest you use the quadratic formula.

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.

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.

Put the quadratic equation into standard form; identify the coefficients (a, b, c), replace them in the equation, do the calculations.
