Solving Quadratics

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

Solve by factoring

• A
• B
• C
• D

solve:  
4x²+16x+15=0

• -5/2,-3/2
• (2x+5)(2x+3)
• -10,-6
• 5/2, 3/2

What is another word for zeros?

• y-intercepts
• roots
• vertex
• axis of symmetry

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

• x = 7/2, x = -6
• x = -5/2, x =5
• x = -3/7, x =6
• x = -5/2, x = 7

The discriminant is

• aX²  + bX  +  c
• b - 4ac
• b² - 4ac
• b² + 4ac

For the function below, is the discriminant positive, negative, or zero?
