Question 43032: I have worked out most of my questions tonight and this one is just stumping me for some reason it is the last question so maybe it is meant to be hard. I am ppretty sure it can be done. This is under factoring trinomials with lead coefficients other than 1 in my book I am pretty sure.
Chris

Question 43060: Here are a few problems that I am grindin my teeth at:
Factor completely:
3a^2 - 27b^2
would the answer be 3(a * a) - (3 * 3* 3)(b * b)?
# 2 x^2 - 15wy + 3xy - 5 wx
would it be (x8x) - (3*5wy) + 3xy - 5 wx?
# 3
9x^2 - 36y^2
would it be (3*3)(x*x) - 3*3*2*2(y*y)?
# 4
3x^2 + 2x - 8
would it be 5 (x*x + x) -8
