Quadratic Formula Practice

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

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

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5

For y = 4x² +8x -3, find b² - 4ac.
