Question 944838: How can you tell if an algebraic fraction is a quadratic, difference of two squares or highest common factor? I'm fine once I know what type of sum it is. Eg: 3x²+9x/ x+3
That just confuses me.

The numerator is quadratic; but the denominator is linear. Your rational expression can be simplified.

%283x%5E2%2B9x%29%2F%28x%2B3%29

%283x%28x%2B3%29%29%2F%28x%2B3%29

This is like 3x but with the restriction, x%3C%3E-3.
