Honestly, \"%28x%2B2%29%2F%28x-2%29\" is a perfectly valid answer. If I were grading your homework, then I would accept that answer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here's what they did to get \"1%2B4%2F%28x-2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "--------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x%2B2%29%2F%28x-2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x%2B2%2B2-2%29%2F%28x-2%29\" Notice the +2-2 up top. This is equal to 0. Adding 0 doesn't change the expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x-2%2B2%2B2%29%2F%28x-2%29\" move the -2 next to the x to get \"x-2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28%28x-2%29%2B%282%2B2%29%29%2F%28x-2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28%28x-2%29%2B%284%29%29%2F%28x-2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x-2%29%2F%28x-2%29%2B4%2F%28x-2%29\" Break up the fraction using the rule \"%28a%2Bb%29%2Fc+=+a%2Fc+%2B+b%2Fc\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1%2B4%2F%28x-2%29\" Use the rule \"x%2Fx+=+1\" (x is nonzero)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So that shows how \"%28x%2B2%29%2F%28x-2%29\" is equivalent to \"1%2B4%2F%28x-2%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Side Note: you can also use polynomial long division or synthetic division to find that \"%28x%2B2%29%2F%28x-2%29=1%2B4%2F%28x-2%29\"
