[x^-2 + x^-1] / [x^2 - x^-1] \n" ); document.write( "= [1/x^2 + 1/x]/[x^2-1/x] \n" ); document.write( "= [(x+1)/x^2]/[(x^3-1)/x] \n" ); document.write( "= [(x+1)/x^2][x/(x^3-1)] \n" ); document.write( "= [x(x+1)]/[x^2(x^3-1)] \n" ); document.write( "= (x+1)/(x^3-1) \n" ); document.write( ".... Perhaps you have made a mistake copying the problem. It makes better sense if the equation was specified as x^-2 + x^-1 divided by x^-2 - x^-1 \n" ); document.write( " |
