You can put this solution on YOUR website!
Assume you mean:
\n" ); document.write( " $\"2%2F%28%285x%2B+15%29%29\"$ + $\"5%2F%28%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "We can factor the 1st denominator
\n" ); document.write( " $\"2%2F%285%28x%2B3%29%29\"$ + $\"5%2F%28%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "The common denominator is 5(x+3), so we have:
\n" ); document.write( " $\"%28%282+%2B+5%285%29%29%29%2F%285%28x%2B3%29%29\"$ = $\"27%2F%285%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( " $\"%28%28x%2B2%29%29%2F%28%28x%5E2%2B4x+%2B3%29%29\"$ - $\"6%2F%28%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "The first denominator will factor here also:
\n" ); document.write( " $\"%28%28x%2B2%29%29%2F%28%28x%2B1%29%28x%2B3%29%29\"$ - $\"6%2F%28%28x%2B3%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "The common denominator will be (x+1)(x+3), right?
\n" ); document.write( " $\"%28%28x%2B2%29+-+6%28x%2B1%29%29%2F%28%28x%2B1%29%28x%2B3%29%29\"$ = $\"%28%28x+%2B+2+-+6x+-+6%29%29%2F%28%28x%2B1%29%28x%2B3%29%29\"$ = $\"%28%28-5x+-+4%29%29%2F%28%28x%2B1%29%28x%2B3%29%29\"$
