x^2(x+1)/x(x+1) , I'm presuming you want to simplify this equation?
So first you can simplify it a little by noticing the fact that x^2/x = x. So,
x^2(x + 1) / x(x + 1) = x(x + 1) / (x + 1)
Then you can see that (x + 1)/(x + 1) = 1. So,
x(x + 1) / (x + 1) = x
So the final answer is:
x^2(x + 1) / x(x + 1) = x
