Look at \"2000=highlight_red%28+-16%2At%5E2%2B1000%2At%2B50+%29\".
Moved these terms to the left \"highlight_green%28+16%2At%5E2+%29\",\"highlight_green%28+-1000%2At+%29\",\"highlight_green%28+-50+%29\"
It becomes .

Look at \"highlight_red%28+2000+%29%2B16%2At%5E2-1000%2At-highlight_red%28+50+%29=0\".
Added fractions or integers together
It becomes \"highlight_green%28+1950+%29%2B16%2At%5E2-1000%2At=0\".
