DETAILED EXPLANATION

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.
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.
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.
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
