Quadratic Formula Review

• a = 9, b = 3, c = 11

• a = 9, b = -3, c = 11

• a = 11, b = -3, c = 9

• a = 0, b = 13, c = -6

• a = 1, b = 13, c = 0

• a = 1, b = 13, c =6

• a = 1, b = 13, c = -6

• a = -1, b = 17, c = 40

• a = 1, c = 17, b = 40

• a = -1, c = 17, b = 39

• a = -1, c = 17, b = 41

• a = 3, b = 1, c = 1

• a = 3, b = 1, c = -1

• a = 3, b = -1, c = 1

• a = 3, b = -1, c = -1

Steps 3 & 4: Plug a = 3, b = -1, and c = -1 into the quadratic formula shell.
