Question 356193: I have been trying to work on my homework I have been going multiplying and diving expressions, but for some reason I cant even do something more simple which would be Adding expressions.
One of my questions is
1 over x squared - x equals 1 over x

1%2F%28x%5E2-x%29=1%2Fx
You need to use a common denominator, x%5E2-x=x%28x-1%29
1%2F%28x%5E2-x%29=%28x-1%29%2F%28x%28x-1%29%29
1%2F%28x%5E2-x%29-%28x-1%29%2F%28x%28x-1%29%29=0
%281-%28x-1%29%29%2F%28x%28x-1%29%29=0
%281-x%2B1%29%2F%28x%28x-1%29%29=0
%282-x%29%2F%28x%28x-1%29%29=0
The expression equals zero when,
2-x=0
highlight%28x=2%29
