You can put this solution on YOUR website!
You're basically looking for 2 numbers that add to -7 and multiply to -8. So you could have 1,8 (1*8=8 1+8=9) -1,8 ((-1)8=-8 8-1=7) etc. You would continue this until you have the right combo. So you could factor it to
\n" ); document.write( " $\"%28x%2B1%29%28x-8%29\"$
\n" ); document.write( "If you were to foil it, you would get
\n" ); document.write( " $\"%28x%2B1%29%28x-8%29=x%5E2-8x%2Bx-8=x%5E2-7x-8\"$ Which is our original problem and this verifies our answer. \n" ); document.write( "
