  • Graphical form: %28t%5E2-6t%2B7%29-%285t%5E3-3t-2%29 simplifies to t%5E2-3%2At-5%2At%5E3%2B9
  • Text form: (t^2-6t+7)-(5t^3-3t-2) simplifies to t^2-3*t-5*t^3+9
  • Cartoon (animation) form: simplify_cartoon%28+%28t%5E2-6t%2B7%29-%285t%5E3-3t-2%29+%29
    For tutors: simplify_cartoon( (t^2-6t+7)-(5t^3-3t-2) )

DETAILED EXPLANATION

Look at highlight_red%28+%28t%5E2-6%2At%2B7%29+%29-%285%2At%5E3-3%2At-2%29.
Remove unneeded parentheses around terms highlight_red%28+t%5E2+%29,highlight_red%28+-6%2At+%29,highlight_red%28+7+%29
It becomes .
Look at t%5E2-6%2At%2B7-highlight_red%28+%285%2At%5E3-3%2At-2%29+%29.
Remove unneeded parentheses around terms highlight_red%28+-5%2At%5E3+%29,highlight_red%28+3%2At+%29,highlight_red%28+2+%29
It becomes .
Look at t%5E2-6%2At%2Bhighlight_red%28+7+%29-5%2At%5E3%2B3%2At%2Bhighlight_red%28+2+%29.
Added fractions or integers together
It becomes t%5E2-6%2At%2Bhighlight_green%28+9+%29-5%2At%5E3%2B3%2At.
Look at t%5E2-6%2At%2Bhighlight_red%28+9+%29-5%2At%5E3%2B3%2At.
Moved 9 to the right of expression
It becomes t%5E2-6%2At-5%2At%5E3%2B3%2At%2Bhighlight_green%28+9+%29.
Look at t%5E2-highlight_red%28+6%2At+%29-5%2At%5E3%2Bhighlight_red%28+3%2At+%29%2B9.
Eliminated similar terms highlight_red%28+-6%2At+%29,highlight_red%28+3%2At+%29 replacing them with highlight_green%28+%28-6%2B3%29%2At+%29
It becomes t%5E2%2Bhighlight_green%28+%28-6%2B3%29%2At+%29-5%2At%5E3%2B9.
