    \n" ); document.write( "
  • Graphical form: \"3%2A%28-5s-2%29\" simplifies to \"-15%2As-6\"
  • Text form: 3*(-5s-2) simplifies to -15*s-6
  • Cartoon (animation) form: \"simplify_cartoon%28+3%2A%28-5s-2%29+%29\"
    For tutors: simplify_cartoon( 3*(-5s-2) )

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+3%2A%28-5%2As-2%29+%29\".
Expanded term \"3\" by using associative property on \"%28-5%2As-2%29\"
It becomes \"-highlight_green%28+3%2A5%2As+%29-highlight_green%28+3%2A2+%29\".
\n" ); document.write( "
Look at \"-highlight_red%28+3+%29%2Ahighlight_red%28+5+%29%2As-3%2A2\".
Multiplied numerator integers
It becomes \"-highlight_green%28+15+%29%2As-3%2A2\".
\n" ); document.write( "
Look at \"-15%2As-highlight_red%28+3+%29%2Ahighlight_red%28+2+%29\".
Multiplied numerator integers
It becomes \"-15%2As-highlight_green%28+6+%29\".
Result: \"-15%2As-6\"

Done!

\n" ); document.write( "\n" ); document.write( "You guys are both correct.
\n" ); document.write( "You just simplified more (which is better)
\n" ); document.write( "I don't know why your tutor didn't simplify even more, that's odd.
\n" ); document.write( "Hope this helps! \n" ); document.write( "
