Cevap:

#y '= (-2x (x ^ 2 + 5) ^ 2-2 (-x ^ 2 + 5) (x ^ 2 + 5) (2x)) / ((x ^ 2 + 5) ^ 2) ^ 2 #

Açıklama:

#y '= (-2x (x ^ 2 + 5) ^ 2-2 (-x ^ 2 + 5) (x ^ 2 + 5) (2x)) / ((x ^ 2 + 5) ^ 2) ^ 2 #

#y '= (-2x (x ^ 4 + 10x +25) - 4x (-x ^ 4 - iptal (5x ^ 2) + iptal (5x ^ 2) + 25)) / ((x ^ 2 + 5) ^ 4 #

#y '= (-2x ^ 5 - 20x ^ 2-50x + 4x ^ 5 - 100x) / ((x ^ 2 + 5) ^ 4 #

#y '= (2x ^ 5 - 20x ^ 2-150x) / ((x ^ 2 + 5) ^ 4 #
