Quadratic Formula

Front

Solve Using the Quadratic Formula
 x² + 4x - 40 = -8

Back

-8 & 4

Front

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter: a=0, b=5, c=7, a=1, b=5, c=7, a=7, b=5, c=1

Back

a=1, b=5, c=7

The first step in solving quadratic equations is to . . .

Back

write the equation in standard form

Front

Why are quadratic equations set equal to zero?

Back

Because we are trying to find the x-intercepts and that happens when y=0.
