The question I'm having difficulty with is this one: x^2+6x+8/x^2+x-2 divided by x+4/2x+4

You can put this solution on YOUR website!
x^2+6x+8/x^2+x-2 divided by x+4/2x+4
\n" ); document.write( ":
\n" ); document.write( "remember that when you divide you invert the dividing fraction and multiply:
\n" ); document.write( " $\"%28x%5E2%2B6x%2B8%29%2F%28x%5E2%2Bx-2%29\"$ * $\"%282x%2B4%29%2F%28x%2B4%29\"$
\n" ); document.write( ":
\n" ); document.write( "You can factor here:
\n" ); document.write( " $\"%28%28x%2B4%29%28x%2B2%29%29%2F%28%28x%2B2%29%28x-1%29%29\"$ * $\"%282%28x%2B2%29%29%2F%28x%2B4%29\"$
\n" ); document.write( ":
\n" ); document.write( "Notice that you can cancel the (x+4)'s and the (x+2)'s, leaving us with:
\n" ); document.write( " $\"1%2F%28x-1%29%29\"$ * x(x+2)
\n" ); document.write( ":
\n" ); document.write( " $\"%28x%28x%2B2%29%29%2F%28x-1%29%29\"$ is our results \n" ); document.write( "

\n" );
