Calculating Quadratics Practice

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5

Identify the 'b' value: y = 16x² -8x -24

• 16

• -8

• 8

• -24

What is the "c" value in the equation

4x² = 76 ?

• 4

• 76

• 0

• -76

• x = -1 and -3

• x = 1 and 3

• x = 1 and -3

• x = -1 and 3

What are the roots?
2x² + 2x - 12 = 0

• x = 3 ; x = -3

• x = 12 ; x =  -12

• x = -3 ; x = 2

• x = -2 ; x = 2

What are the zeros of the function?
f(x) = x² + x - 20

• x = 5 ; x = -4

• x = -20 ; x = 0

• x = -5 ; x = 4

• x = 20; x = 0
