Question 190077: Factor out the GCF
2x^3y+14x^2y-18xy
Answer by feliz1965(151)   (Show Source):
You can put this solution on YOUR website! I can see that x and y appear in each term.
I can pull out 2 because it can evenly fit into itself, 14 and -18.
I also can pull out x because it can evenly fit into itself, x^3 and x^2.
I will also pull out a y because it can evenly fit into itself.
We now divide part by part.
2/2 = 1
14/2 = 7
-18/2 = -9
x^3/x = x^2
x^2/x = x
x/x = 1
y/y = 1
Final answer: 2xy(x^2 + 7x - 9)
