You can put this solution on YOUR website!
x^2 - x/ x^2 + 3x + 2 / x^2-1/x^2+2X
:
Assume you mean:
%28%28x%5E2-x%29%29%2F%28%28x%5E2%2B3x%2B2%29%29
-------------
%28%28x%5E2-1%29%29%2F%28%28x%5E2%2B2x%29%29
:
Can be factored to:
%28x%28x-1%29%29%2F%28%28x%2B2%29%28x%2B1%29%29
-------------
%28%28x-1%29%28x%2B1%29%29%2F%28x%28x%2B2%29%29
:
Invert the dividing fraction and multiply:
%28x%28x-1%29%29%2F%28%28x%2B2%29%28x%2B1%29%29 * %28x%28x%2B2%29%29%2F%28%28x-1%29%28x%2B1%29%29
:
CAncel the (x-1)'s and (x+2)'s and you have:
x%2F%28%28x%2B1%29%29 * x%2F%28%28x%2B1%29%29 = x%5E2%2F%28%28x%2B1%29%5E2%29
