rozłóż wielomian w na czynniki a) w(x)= x3-2x2-2x=4 b) w(x)=2x3-3x2=4x-6 c) w(x)= x4=x3-4x2-4x d) w(x)=5x3=x2-15x-3
a) w(x)= x3-2x2-2x=4
w(x)= x3-2x2-2x-4=0
w(x)=x2(x-2)-2)(x-2)
w(x)=(x-2)(x2-2)
w(x)=(x-2)(x-pier z 2)(x+ pier z 2)
b) w(x)=2x3-3x2=4x-6
w(x)=2x3-3x2-4x+6
w(x)=x2(2x-3)+2(2x-3)
w(x)=(2x-3)(x2+2)
c) w(x)= x4=x3-4x2-4x
w(x)=x4-x3+4x2+4x
w(x)=x3(x-1)-4(x-1)
w(x)=(x-1)(x3-1)
d) w(x)=5x3=x2-15x-3
w(x)=x2(5x-1)-3(5x-1)
w(x)=(5x-1)(x-pier z 3)(x+ pier z 3)
