11.6 Intro to Solving by Using the Quadratic Formula

In the equation
y = x² +5x +7, match each leading coefficient with its correct letter 

• a=0, b=5, c=7
• a=1, b=5, c=7
• a=7, b=5, c=1

find x for
2x²-8x-24=0

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

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

What is "b" in the equation 3x² −7 = 0 ?

• 3

• 7

• 0

• 10
