  • Graphical form: \"-%282%29%5E2-10%2A%282%29%2B6\" simplifies to \"-18\"
  • Text form: -(2)^2-10*(2)+6 simplifies to -18
  • Cartoon (animation) form: \"simplify_cartoon%28+-%282%29%5E2-10%2A%282%29%2B6+%29\"
    For tutors: simplify_cartoon( -(2)^2-10*(2)+6 )

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"-%282%29%5E2-highlight_red%28+10%2A%28highlight_red%28+2+%29%29+%29%2B6\".
Remove unneeded parentheses around factor \"highlight_red%28+2+%29\"
It becomes \"-%282%29%5E2-10%2Ahighlight_green%28+2+%29%2B6\".
\n" ); document.write( "
Look at \"-highlight_red%28+%282%29+%29%5Ehighlight_red%28+2+%29-10%2A2%2B6\".
Replace constants in factor: \"highlight_red%28+%282%29+%29\",\"highlight_red%28+2+%29\" with \"highlight_green%28+4+%29\"
It becomes \"-highlight_green%28+4+%29-10%2A2%2B6\".
\n" ); document.write( "
Look at \"-4-highlight_red%28+10+%29%2Ahighlight_red%28+2+%29%2B6\".
Multiplied numerator integers
It becomes \"-4-highlight_green%28+20+%29%2B6\".
\n" ); document.write( "
Look at \"-highlight_red%28+4+%29-highlight_red%28+20+%29%2Bhighlight_red%28+6+%29\".
Added fractions or integers together
It becomes \"highlight_green%28+-18+%29\".
\n" ); document.write( "
Look at \"highlight_red%28+-18+%29\".
Removed extra sign in front of \"-18\"
It becomes \"-highlight_green%28+18+%29\".
Result: \"-18\"

Done!

\n" ); document.write( "\n" ); document.write( "Your answer was close, but what you did wrong was you plugged in -2 in for x in the first term, while x is 2.
