Okay, I have two questions to ask about Here's the first one...
1) Express as a simple fraction: ( (1/y-k)-(1/y) ) / k
I got rid of the k denominator by multiplying it to the top ones, so now I have this...
1/yk-k^2 - 1/yk
But I have no clue what to do after this step. I'm unsure how to either get the other side to have a +k^2 so I could actually turn that into one fraction. Thanks
Here's my second question:
2) x(x-1)^(-1/2) + 2(x-1)^1/2
I understand that I can change (x-1)^(1/2) to the square root of (x-1)... But what would (x-1)^(-1/2) change to?
Thanks for you help
