Quadratic Formula

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

Name "c" for the equation
4x² - 5x + 7 = 10

• 7
• 17
• -5
• -3

Identify the values of a, b, and c

3m² - 14 = 11m

• a=3, b=-11, c=-14

• a=3, b=-14, c=11

• a=3, b=11, c=-14

• a=3, b=-14, c=11

Use the graph to determine the solutions.
