Question

Zakończ rozkładanie wielomianu w na czynniki:
A. w(x)= x^3 - 2x^2 + x - 2= x^2 (x-2) + (x-2)
B. w(x)= 2x^3 + 2x^2 + 3x + 3= 2x^2 (x+1) + 3 (x+1)
C. w(x)= x^3 - 2x^2 - 4x + 8= x^2 (x-2) - 4 (x-2)
D. w(x)= 4x^3 + 12x^2 - x - 3= 4x^2 (x+3) - (x+3)

Kolejny raz prosze o pomoc, dam NAJ :)

Answer 1

A) w(x)=(x-2)(x^2+1)
b) w(x)=(x+1)(2x^2+3)
c) w(x) = (x-2)(x^2-4)=(x-2)(x-2)(x+2)
d) w(x) =(x+3)(4x^2-1)=(x+3)(2x-1)(2x+1)

a^2-b^2=(a-b)(a+b)
