Question

A) W(x)= x³-x²+x-1
b) W(x)=x³-2x²-2x+4
c)W(x)=x³-3x²+2x
d)W(x)=x (do szostej) +7x( do piatej)+6x( do czwartej)

Answer 1

A) (x+1)(x-1)²


B) W(x)=x³-2x²-2x+4
łączymy 1 z 2 i 3 z 4
czyli: w(x)=x²(x-2)-2(x-2)
w(X)=(x-2)(x²-2)
w(x)=(x-2)(x-√2)(x+√2)

C) W(x) = x³ - 3x²-2x +6
W(x) = x² ( x -3) - 2(x -3)
W(x) = (x -3)( x² -2)
W(x) = (x-3)( x - √2)(x + √2)
