Question 1023872: My math book and the algebra app always leave problems unfinished. They say [(a^2-b^2)/(c+d)/(a-b)/(c^2-d^2)]=[(a+b)(c-d)]/(1). I think the answer is (ac-ad+bc-bd). Can you explain why everything leaves the problem unfinished? Answer by FrankM(1040) (Show Source):
You can put this solution on YOUR website! The key thing to understand this is that factors to
Once you see this, the a-b factor in both numerator and denominator cancel. Same process for the c-d factor.
