Y = (2x + 4) (- x + 5) (- x + 1) 'in standart formu nedir?

Cevap:

#y = -2x ^ 3-8x ^ 2-14x + 1 #

Açıklama:

#y = (-2x ^ 2 + 10x-4x + 20) (- x + 1) #

#y = (-2x ^ 2 + 6x + 20) (- x + 1) #

#y = -2x ^ 3-2x ^ 2-6x ^ 2 + 6x-20x + 1 #

#y = -2x ^ 3-8x ^ 2-14x + 1 #

Her zaman önce sert olanı çarpanlara ayırın, aksi halde çarpan soldan sağa.

Cevap:

#color (mavi) (y = 2 x ^ 3-8x ^ 2-14x + 20 #

Açıklama:

• y = (+ 4 2x) (- x + 5) (- x + 1) #

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

#color (beyaz) (aaaaaaaaaa) ## xx altı çizili (-x + 5) #

#color (beyaz) (aaaaaaaaaaa) ## -2x ^ 2-4x #

#color (beyaz) (aaaaaaaaaaaaaaaaa) ## 10x + 20 #

#color (beyaz) (aaaaaaaaaaa) ##overline (2x ^ 2 + 20 + 6x) #

#color (beyaz) (aaaaaaaa) ## xx -x + 1 #

#color (beyaz) (aaaaaaaaaaaa) ##overline (2x ^ 3-6x ^ 2-20x) #

#color (beyaz) (aaaaaaaaaaaaaaa) ## -2x ^ 2 + 6x + 20 #

#color (beyaz) (aaaaaaaa) ##color (mavi) (y = overline (2x ^ 3-8x ^ 2-14x + 20) #
