You can put this solution on YOUR website!
first let me remind you that if you pull a number out, as you did in the second one, it would have to be divisable into the rest of the equation equally. If you pull a two out as you did, the rest of the numbers in the equation must be multiples of 2 for that to work, so I do not believe that the second one would work at all. I would use the first one. You started out exactly right. I assume your trouble was with the reverse foil you were using on 2x^2-7x+3, in this case it does work out. I got
\n" ); document.write( "(2x-1)(x-3) it takes some figuring when you have a number in front of the x^2.
\n" ); document.write( "In your equation, the above was divided by (x+3)(x-3), as you can tell the (x-3) will cancel and you would be left with
\n" ); document.write( "2x-1/x+3\r
\n" ); document.write( "\n" ); document.write( "hope this helps
