You can put this solution on YOUR website!
The problem can be re-written like this:
\n" ); document.write( " $\"%287m%5E2-5m-8%29-%285m%5E2%2B2m%2B9%29\"$
\n" ); document.write( "The tricky thing is that minus sign in front of the (5m^2+2m+9). We ultimately want to simplify this by combining like terms. Think of that minus sign as a -1 multiplying each of the terms inside (5m^2+2m+9). Multiplying through by that -1 will allow us to combine terms later:
\n" ); document.write( " $\"7m%5E2-5m-8-5m%5E2-2m-9\"$
\n" ); document.write( "Now you can combine the m^2, m, and whole number terms like this:
\n" ); document.write( " $\"highlight%282m%5E2-7m-17%29\"$
\n" ); document.write( "And you are done.
