DETAILED EXPLANATION

Look at 8%2Ahighlight_red%28+x+%29-9%2Ax%2B2%2A%28-3%2Ax-4%29.
Replaced x with -8
It becomes 8%2Ahighlight_green%28+-8+%29-9%2Ax%2B2%2A%28-3%2Ax-4%29.
Look at 8%2A-8-9%2Ahighlight_red%28+x+%29%2B2%2A%28-3%2Ax-4%29.
Replaced x with -8
It becomes 8%2A-8-9%2Ahighlight_green%28+-8+%29%2B2%2A%28-3%2Ax-4%29.
Look at 8%2A-8-9%2A-8%2B2%2A%28-3%2Ahighlight_red%28+x+%29-4%29.
Replaced x with -8
It becomes 8%2A-8-9%2A-8%2B2%2A%28-3%2Ahighlight_green%28+-8+%29-4%29.
Look at 8%2A-8-9%2A-8%2B2%2A%28-highlight_red%28+3%2A-8+%29-highlight_red%28+4+%29%29.
Replace constants in expression: highlight_red%28+-3%2A-8+%29,highlight_red%28+-4+%29 with highlight_green%28+20+%29
It becomes 8%2A-8-9%2A-8%2B2%2A%28highlight_green%28+20+%29%29.
Look at highlight_red%28+8%2A-8+%29-highlight_red%28+9%2A-8+%29%2Bhighlight_red%28+2%2A%2820%29+%29.
Replace constants in expression: highlight_red%28+8%2A-8+%29,highlight_red%28+-9%2A-8+%29,highlight_red%28+2%2A%2820%29+%29 with highlight_green%28+48+%29
