Solving Quadratics Review

Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3

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

Find the discriminant and determine how many zeros exist for the following function: 
x² - 6x + 5 = 0

• -56; No real roots
• 16; Two real solutions
• -56; Two real solutions
• 16; No real roots

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

• 16
• 8
• -8
• -24

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

• 16
• -8
• 8
• -24

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

• 16
• -8
• 24
• -24

b²  would equal: y = 2x² -x -3

• 2
• -1
• 1
• -3

4ac would equal:  y = 2x² -x -3

• -12
• 8
• -24
• -1
