What are the x- intercepts?

• (0,0) and (0,4)

• (0,0) and (4,0)

• y= 0

• x= 2

Use the graph to determine the solutions.

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

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

Identify a, b, and c in: x²−6x+14

• a=3,b=5,c=9

• a=1,b=-6,c=14

• a=1,b=-6,c=-14

• a=1,b=6,c=14

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 x for
2x²-8x-24=0

• x= 6, -2
• x= 2, -6
• x= 4, 2
• x= 2, 6

Solve using the Quadratic Formula:
x² + 4x + 3 = 0

• x = 1 and x = 3
• x = 6 and x = -2
• x = -1 and x = -3
