Sagot:

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

Paliwanag:

#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 #

Palaging isaalang-alang ang mas mahirap isa muna, kung hindi man, kadahilanan na pakaliwa sa kanan.
