Front

What is this formula?

Back

This is the quadratic formula.

Front

Determine the values of a, b, and c for the quadratic equation: 4x² – 8x = 3 (right side should = 0)

Back

a = 4, b = -8, c = -3

Front

Solve by factoring: x² - 9x + 20 = 0

Back

x = 4 and x = 5

Front

Solve by using the quadratic formula: 7x² - 26x - 8 = 0

Back

x = 4 and x = -2/7

Front

2x² + 7x - 15 = 0

Back

x = -5 and x = 1.5

Front

3x² = 16x + 12

Back

x = -0.67 and x = 6

Front

2x² = -x + 3

Back

x = -1.5 and x = 1

Front

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

Back

x = -8 and x = 4

Front

Solve using the quadratic formula: 2x² - 9x - 35 = 0

Back

x = -5/2 and x = 7

Front

n² = 9n - 20

Back

n = 4 and n = 5
