(one /(four *(x + two)))*(two *x + eight) - (x + four)^ two /(four *(x + two)^ two) = zero
(1 divide by (4 multiply by (x plus 2))) multiply by (2 multiply by x plus 8) minus (x plus 4) squared divide by (4 multiply by (x plus 2) squared ) equally 0
(one divide by (four multiply by (x plus two))) multiply by (two multiply by x plus eight) minus (x plus four) to the power of two divide by (four multiply by (x plus two) to the power of two) equally zero
