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 should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form
• Write down: a=1, b=6, c=-13
• Make it equal 0 by subtracting 3 on each side
• Type it all in a calculator.

Set the following to equal zero.
8p² = - 56p - 48

• 8p² + 56p = -48
• 112p³ = 0
• 64p + 48 = 0
• 8p² + 56p + 48 = 0

Use the quadratic formula to solve 2x² + 2x - 12=0

• -2, 3

• 2, 3

• 2, -3

• -2, -3
