Day 4 Homework : Omit # 11, 15, 18
Remember to show some work. Do NOT just put answers! 
Factor: (Some of these may be
prime)
34. x2 + 8x + 15
Solve: (we have 5 methods…do
not say “prime!!!”)
0 = x2 + 8x + 15
Graph (use a separate sheet of
graph paper):
y = x2 + 8x + 15
35. x2 + 8x – 12
x2 + 8x = 12
y = x2 + 8x – 12
36. x2 + 8x
x2 = - 8x
y = x2 + 8x
37. -x2 + 9x – 18
-x2 + 9x = 18
y = -x2 + 9x – 18
