You can put this solution on YOUR website!
I assume the question is just to simplify the expression.
\n" ); document.write( "Let me re-write it first, since all my keys work :-)\r
\n" ); document.write( "\n" ); document.write( "\"%283a%5E2-2a%2B7%29%2B%28a%5E2-3a-4%29\"\r
\n" ); document.write( "\n" ); document.write( "To simplify this expression, you need to combine \"like terms.\"
\n" ); document.write( "\"Like terms\" are those terms that have their variable raised to
\n" ); document.write( "the same exponent. For example, 3a^2 and a^2 are \"like terms.\"\r
\n" ); document.write( "\n" ); document.write( "So, you can re-write this as:
\n" ); document.write( "\"4a%5E2-5a%2B3\"\r
\n" ); document.write( "\n" ); document.write( "If, like I said, the problem was jusst to simplify the expression,
\n" ); document.write( "then that is the answer.
\n" ); document.write( "
\n" );
