Question 971862: I am adding rational expressions but have run into a snag. here is the expression, I hope you can help me.
x^2-16x-45/x^2-3x-18 + x^2-2x-27/x^2-3x-18
My snag is, I can't figure out how to factor the first numerator because I don"t see any terms that make the product -45 = to the sum of -16.
I hope I explained it right. Can you help me? Answer by Alan3354(69443) (Show Source):
