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.

• a = 0

  b = 5

  c = -9

• a = 1

  b = -5

  c = 9

• a = 0

  b = -5

  c = -9

• a = 1

  b = -5

  c = -9

Answer explanation

Remember, the equation MUST be set equal to zero BEFORE you can identify the values of a, b, c.
