combining algebra fractionshey all i have very basic question but i dont understand why my answer is different i get the answer however the book says why cant we remove the d^2? is it because dividing both negative numbers makes a positive or something S: Last edited by bronxsystem (20130716 08:42:08) #2 20130716 10:08:24

Re: combining algebra fractionsHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130716 13:43:46
Re: combining algebra fractionshow would you write the final answer? because if i just change the numbers its just 1/1 right S: sorry i should stop posting after ive stayed up all night Last edited by bronxsystem (20130716 14:47:58) #5 20130716 15:06:38
