Solve Quadratic Find the Mistake

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

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x = 3

*HINT: Don't forget to first set the equation equal to zero.

• 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 using the quadratic formula :

x² - 7x + 12 = 0

• x = 3, -4

• x = -3, 4

• x = 3, 4

• x = -3, -4
