#:. renk (mavi) (y = 8x ^ 3 + 20x ^ 2 + 70x + 23 #

Açıklama:

• y = (2x + 3) ^ 3- (4 x-2) ^ 2 #

İlk basitleştirmek # (2x + 3) ^ 3 #

#color (beyaz) (aaaaaaaaaaaaa) ## 2x + 3 #

#color (beyaz) (aaaaaaaaaaa) ## altı çizili (xx 2x + 3) #

#color (beyaz) (aaaaaaaaaaaaa) ## 4x ^ 2 + 6x #

#color (beyaz) (AAAAAAAAAAAAAAAAAAA) ## 6x + 9 #

#color (beyaz) (aaaaaaaaaaaaa) ##overline (4x ^ 2 + 12x + 9) #

#color (beyaz) (aaaaaaaaaaa) ## xx 2x + 3 #

#color (beyaz) (aaaaaaaaaaaaa) ##overline (8x ^ 3 + 24x ^ + 18x 2) #

#color (beyaz) (aaaaaaaaaaaaaaaaaa) ## 12x ^ 2 + 36x + 27 #

#color (beyaz) (aaaaaaaaaaaaa) ##overline (renk (mor) (8x ^ 3 + 36x ^ 2 + 54x + 27) #

O zaman basitleştir #color (yeşil) ((4x-2) ^ 2 #

#color (yeşil) (= (4x-2) (4x-2)) #

#:. renk (yeşil) ((4x-2) ^ 2 = 16x ^ 2-16x + 4 #

#color (mor) ((2x + 3) ^ 3 = 8x ^ 3 + 36x ^ 2 + 54x + 27 #

#:. y = 8x ^ 3 + 36x ^ 2 + 54x + 27- (16x ^ 2-16x + 4) #

#:. renk (turuncu) (y = 8x ^ 3 + 36x ^ 2 + 54x + 27-16x ^ 2 + 16x-4) #

#:. renk (mavi) (y = 8x ^ 3 + 20x ^ 2 + 70x + 23 #
