Question

Part A: Factor 3x2y2 − 2xy2 − 8y2. Show your work. (4 points) Part B: Factor x2 + 10x + 25. Show your work. (3 points) Part C: Factor x2 − 36. Show your work. (3 points) (10 points)

Answer 1

These are what b and c would look like.

2. x^2+19x+25
=(x^2+5x) (5x+25)
x(x+5) and 5(x+5)
x(x+5) + 5(x+5)
(x+5) (x+5)
(x+5)^2

3. x^2-36
6*6=36
-6*6=-36
(x+6) (x-6)
