You can put this solution on YOUR website!
Your second answer is correct.
\n" ); document.write( ".
\n" ); document.write( "The answer to the first problem is x-1 and you get it as follows:
\n" ); document.write( ".
\n" ); document.write( "Given:
\n" ); document.write( ".
\n" ); document.write( "\"x%5E2%2F%28x%2B10%29+%2B+%289x+-+10%29%2F%28x%2B10%29\"
\n" ); document.write( ".
\n" ); document.write( "Since both parts of this problem have the common denominator of x + 10, the numerators
\n" ); document.write( "can be added and the result placed over the common denominator to get:
\n" ); document.write( ".
\n" ); document.write( "\"%28x%5E2+%2B+9x+-+10%29%2F%28x%2B10%29\"
\n" ); document.write( ".
\n" ); document.write( "The numerator can be factored. When you factor it the result is:
\n" ); document.write( ".
\n" ); document.write( "\"%28%28x+-1%29%28x%2B10%29%29%2F%28x%2B10%29\"
\n" ); document.write( ".
\n" ); document.write( "Now cancel the common factors of x + 10 in the numerator and x+10 in the denominator:
\n" ); document.write( ".
\n" ); document.write( "\"%28%28x+-1%29%28cross%28x%2B10%29%29%29%2F%28cross%28x%2B10%29%29\"
\n" ); document.write( ".
\n" ); document.write( "and you are left with the answer:
\n" ); document.write( ".
\n" ); document.write( "\"x-1\"
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you find your mistake. I suspect it was in the factoring of the numerator.
\n" ); document.write( ".
\n" ); document.write( "Good job on the second problem. That was a little \"tricky\" to solve.
\n" ); document.write( "
\n" );
