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 are the zeros, roots, solutions to the equation

x² - 2x = 8?

• x = 2 or x = -4

• x = 1 or x = -8

• x = 4 or x = -2

• x = 8 or x = -1

If you wanted to solve this equation, what should you do first?

x² + 6x - 13 = 3

• Factor

• Write down: a=1, b=6, c=-13

• Subtract 3 from both sides

• Add 13 to both sides
