The question says solve:
\n" ); document.write( " $\"x%28x%2B1%29=+-2%28x-4%29=2\"$ <---typing error - the second = sign is supposed to be \"+\"
\n" ); document.write( ".
\n" ); document.write( "This is what I did, can you tell me if I am on the right track, please?
\n" ); document.write( ".
\n" ); document.write( " $\"x%28x%2B1%29=+-2%28x-4%29=2\"$ <--- same comment as above. you correct this OK in the next step
\n" ); document.write( " $\"x%2A2%2B1x=+-2x%2B8%2B2+\"$ <--- no need to show the 1 as the multiplier of x.
\n" ); document.write( " $\"x%2A2%2Bx%2B2x-8-2=0+\"$ <--- OK
\n" ); document.write( " $\"x%2A2%2B3-10=0\"$ <--- should be +3x, not just 3
\n" ); document.write( " $\"%28x%2B5%29%2A%28x-2%29\"$ <---- should show this product as equal to 0
\n" ); document.write( " $\"x%2B5=0\"$ $\"+x-2=0+\"$ <---- OK
\n" ); document.write( " $\"x=-5\"$ and $\"x=-2\"$ <--- the x = -5 is correct but you have a very minor mistake in
\n" ); document.write( "saying x = -2. Check your work on solving x-2 = 0.
\n" ); document.write( ".
\n" ); document.write( "Good job! You seem to understand all the steps you have to do to solve this equation, and
\n" ); document.write( "you also understand factoring quadratic equations. \n" ); document.write( "

\n" );
