Best Answer

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

The quadratic formula is used today to find the solutions to quadratic equations, which are equations of the form ax^2 + bx + c = 0. By using the quadratic formula, we can determine the values of x that satisfy the quadratic equation and represent the points where the graph of the equation intersects the x-axis.

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