The quadratic formula is used all the time to solve quadratic equations, often when the factors are fractions or decimals but sometimes as the first choice of solving method. The quadratic formula is sometimes faster than completing the square or any other factoring methods.

Quadratic formula find:

-x-intercept

-where the parabola cross the x-axis

-roots

-solutions
