Quadratic Formula HW

Identify a, b, and c in: x²−6x+14

• 3,5,9
• 1,-6,14
• 1,-6,-14
• 1,6,14

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

• x = 7 and -2

• x = 7 and 2

• x = -7 and -2

• x = -7 and 2

• x = 1 and -3

• x = -1 and -3

• x = -1 and 3

• x = 1 and 3

• A
• B
• C
• D

What is this formula?

• This is the speed of light formula.
• This is the quadratic formula.
• This is the zero product property.
• This is scary.

• x = -1 and 3

• x = 1 and -3

• No real solution

• x = 1

Why are quadratic equations set equal to zero?

• Because zero is an easy number to work with.

• Because we are trying to find the x-intercepts and that happens when y=0.

• Because setting it equal to zero helps us find the y-intercepts.

• None of the above
