The quadratic formula is x - b b2 - 4 ac2a It is important in algebra where it is used to calculate the roots of quadratic equations. More About Quadratic Function. It makes a parabola a U shape when graphed on a coordinate plane.
A quadratic equation has two solutions called roots.
It is also called an Equation of Degree 2 because of the 2 on the x. X 2 y 2 3x 4 and 4x 2 y 2 2z 2 x y z 4 are examples of quadratic equations of 2 and 3 variables respectively. So it will have something like x 2 But not x 3 etc. The quadratic formula is used in algebra to solve quadratic equations polynomial equations of the second degree.
