Quadratic Formula

What are the values of a, b, and c

7x² + 8x - 3 = 0

• a = 7, b = 8, c = 3

• a = 7, b = 8, c = -3

• a = -3, b = 8, c = 7

• a = 8, b = -3, c = 7

What are the values of a, b, and c?

-x²+5x= -4

• a=1, b = 5, c = -4

• a = -1, b = 5, c = -4

• a = -1, b = 5, c = 4

• a = 1, b = 5, c = 4

What is the value of b² - 4ac ?

2x² - 5x + 1=0

• 17

• -33

• 33

• -17

Use the quadratic formula to solve

x²+5x-24=0

• x= -3 or x = 8

• x = 3 or x = 8

• x = -3 or x = 8

• x=3 or x=-8
