You can put this solution on YOUR website!
what is the simplest form of:
\n" ); document.write( " $\"%28%28x%2B3%29%29%2F%28%28x%5E3-x%5E2-6x%29%29\"$
\n" ); document.write( "-------------
\n" ); document.write( " $\"%28%28x%5E2-9%29%29%2F%28%28x%5E2%2Bx-12%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Remember when you divide fractions, invert the dividing fraction and Multiply
\n" ); document.write( " $\"%28%28x%2B3%29%29%2F%28%28x%5E3-x%5E2-6x%29%29\"$ * $\"%28%28x%5E2%2Bx-12%29%29%2F%28%28x%5E2-9%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Factor as much as we can
\n" ); document.write( " $\"%28%28x%2B3%29%29%2F%28x%28x%5E2-x-6%29%29\"$ * $\"%28%28x%2B4%29%28x-3%29%29%2F%28%28x-3%29%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "the first denominator can be factored again
\n" ); document.write( " $\"%28%28x%2B3%29%29%2F%28x%28x-3%29%28x%2B2%29%29\"$ * $\"%28%28x%2B4%29%28x-3%29%29%2F%28%28x-3%29%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Cancel x+3 and x-3, in the 2nd denominator
\n" ); document.write( " $\"1%2F%28x%28x-3%29%28x%2B2%29%29\"$ * (x+4) = $\"%28%28x%2B4%29%29%2F%28x%28x-3%29%28x%2B2%29%29\"$ ; about all you can do with it.
