\n" ); document.write( "This is what I have come up with so far: factoring out the equations I get 4(x-9)/x(x+1)multiplied by 3x/9-x. I can cancel out one x and I can also cancel out the 9-x and the x-9 which will give me a -1. This leaves me with the following equation
\n" ); document.write( "12/-1(x+1) which equals 12/-x-1. My question is this: what do I do with the negative coefficient? do I multipy by a -1? and would this give me -12/x+1 or 12/x+1.\r

You can put this solution on YOUR website!
Will give you -12/(x+1)\r

\n" ); document.write( "Every fraction has three signs:
\n" ); document.write( "sign of the fraction
\n" ); document.write( "sign of the numerator
\n" ); document.write( "sign of the denominator\r
\n" ); document.write( "\n" ); document.write( "You may change any two of these signs and still
\n" ); document.write( "have the original fraction.\r
