First of all you rearrange the problem so that the same variables are together (remember to keep the sign in-front of the coefficient with it)... This would make the problem look like... 4<u>x^2</u> / 8<u>x^2</u> * 4<u>x^2</u> /2<u>x^2</u> -<em>y^2 + 3y^2 + 4y^2 </em>+ 10xy - 9xy - 5xy Now you would simplify the coefficients based upon the variable... <u /><u>x^2</u> <em>- 10y^2 </em>- 4xy<em>
