Graphical form: $\"%289x%2B5x%29%5E2\"$ simplifies to $\"1764\"$
Text form: (9x+5x)^2 simplifies to 1764
Cartoon (animation) form: $\"simplify_cartoon%28+%289x%2B5x%29%5E2+%29\"$
For tutors: simplify_cartoon( (9x+5x)^2 )

Look at $\"%289%2Ahighlight_red%28+x+%29%2B5%2Ax%29%5E2\"$ .
Replaced x with 3
It becomes $\"%289%2Ahighlight_green%28+3+%29%2B5%2Ax%29%5E2\"$ .
\n" ); document.write( "

Look at $\"%289%2A3%2B5%2Ahighlight_red%28+x+%29%29%5E2\"$ .
Replaced x with 3
It becomes $\"%289%2A3%2B5%2Ahighlight_green%28+3+%29%29%5E2\"$ .
\n" ); document.write( "

Look at $\"%28highlight_red%28+9%2A3+%29%2Bhighlight_red%28+5%2A3+%29%29%5E2\"$ .
Replace constants in expression: $\"highlight_red%28+9%2A3+%29\"$ , $\"highlight_red%28+5%2A3+%29\"$ with $\"highlight_green%28+42+%29\"$
It becomes $\"%28highlight_green%28+42+%29%29%5E2\"$ .
\n" ); document.write( "

Look at $\"highlight_red%28+%2842%29+%29%5Ehighlight_red%28+2+%29\"$ .
Replace constants in factor: $\"highlight_red%28+%2842%29+%29\"$ , $\"highlight_red%28+2+%29\"$ with $\"highlight_green%28+1764+%29\"$
It becomes $\"highlight_green%28+1764+%29\"$ .
Result: $\"1764\"$
