Perhaps you would like it reduced or simplified? Is this the fraction? Learn to write in math talk and use plenty of parentheses Your problem can be interpreted many ways x^(-2)/(x^(-1)-x^(-2)) The key is that x^(-2)=1/x^2 and x^(-1)=1/x so we redo the equation multiply through by x^2/x^2 1/(x-1) BTW we could have multiplied by x^2/x^2 in the beginning without redoing. x^(-2)/(x^(-1)-x^(-2)) 1/x-1 Remember that x^(-2)*x^(2)=x^0=1 so the final result is 1/(x-1)
