Fractions do not have questions and therefore do not have answers.
\n" ); document.write( "Perhaps you would like it reduced or simplified?\r
\n" ); document.write( "\n" ); document.write( "Is this the fraction?
\n" ); document.write( "\"x%5E%28-2%29%2F%28x%5E%28-1%29-x%5E%28-2%29%29\"
\n" ); document.write( "Learn to write in math talk and use plenty of parentheses
\n" ); document.write( "Your problem can be interpreted many ways\r
\n" ); document.write( "\n" ); document.write( "x^(-2)/(x^(-1)-x^(-2))
\n" ); document.write( "The key is that x^(-2)=1/x^2
\n" ); document.write( "and x^(-1)=1/x
\n" ); document.write( "so we redo the equation
\n" ); document.write( "\"%281%2Fx%5E2%29%2F%281%2Fx-1%2Fx%5E2%29\"
\n" ); document.write( "multiply through by x^2/x^2
\n" ); document.write( "1/(x-1)
\n" ); document.write( "BTW we could have multiplied by x^2/x^2 in the beginning without redoing.
\n" ); document.write( "x^(-2)/(x^(-1)-x^(-2))
\n" ); document.write( "1/x-1
\n" ); document.write( "Remember that x^(-2)*x^(2)=x^0=1
\n" ); document.write( "so the final result is 1/(x-1)
\n" ); document.write( " \n" ); document.write( "
\n" );
