DETAILED EXPLANATION

Look at highlight_red%28+3%2Ax%5E2+%29-4.
Since highlight_red%28+3%2Ax%5E2+%29 has zero as a factor, it should be replaced with a zero
Look at 0-4.
Replaced x with 0
It becomes 0-4.
Look at 0-4.
Replace constants in factor: highlight_red%28+0+%29,highlight_red%28+2+%29 with highlight_green%28+0+%29
It becomes 0-4.
Look at 0-highlight_red%28+4+%29.
Replace constants in expression: highlight_red%28+3%2A0+%29,highlight_red%28+-4+%29 with highlight_green%28+-4+%29
It becomes highlight_green%28+-4+%29%2B0.
Look at -4%2Bhighlight_red%28+0+%29.
Remove extraneous zero highlight_red%28+0+%29
It becomes -4.
Look at highlight_red%28+-4+%29.
Removed extra sign in front of -4
It becomes -highlight_green%28+4+%29.
Result: -4
