DETAILED EXPLANATION

Look at highlight_red%28+x+%29%5E2-3%2Ax%2B3.
Replaced x with 4
It becomes highlight_green%28+4+%29%5E2-3%2Ax%2B3.
Look at highlight_red%28+4+%29%5Ehighlight_red%28+2+%29-3%2Ax%2B3.
Replace constants in factor: highlight_red%28+4+%29,highlight_red%28+2+%29 with highlight_green%28+16+%29
It becomes highlight_green%28+16+%29-3%2Ax%2B3.
Look at 16-3%2Ahighlight_red%28+x+%29%2B3.
Replaced x with 4
It becomes 16-3%2Ahighlight_green%28+4+%29%2B3.
Look at highlight_red%28+16+%29-3%2A4%2Bhighlight_red%28+3+%29.
Added fractions or integers together
It becomes highlight_green%28+19+%29-3%2A4.
Look at 19-highlight_red%28+3+%29%2Ahighlight_red%28+4+%29.
Multiplied numerator integers
It becomes 19-highlight_green%28+12+%29.
Look at highlight_red%28+19+%29-highlight_red%28+12+%29.
Added fractions or integers together
It becomes highlight_green%28+7+%29.
Result: 7
