b) w(x)=3x⁴-3x²= 3x²(x²-1)
c) w(x)=2x³+4x²+2x= x(x³+4x+2)
d) w(x)=x⁶+7x⁵+6x⁴=x⁴(x²+7x+6)
e) w(x)=x³-x²+x-1= x²(x-1)+1(x-1)= (x-1)(x²+1)
f) w(x)=x³-2x²-2x+4= x²(x-2)-2(x-2)=(x-2)(x²-2)
g) w(x)=x⁴+x³-4x²-4x=x³(x+1)-4x(x+1)=(x+1)(x³-4x)
h) w(x)=5x³+x²-15x-3= x²(5x+1)-3(5x+1)=(5x+1)(x²-3)
Chyba jestem pierwsza więc liczę na nagrodę :D
Pozdrawiam :D
b)W(x)= 3x²(x²-1)
W(X)-3x²(x-1)(x+1)
c)W(x)=2x(x²+2x+1)
w(x)=2x(x+1)²
d)w(x)= x⁴(x²+7x+6)
W(x)=x⁴(x+1)(x+6)
e)W(x)= x(x²+1)-(x²+1)
W(x)=(x+1)(x-1)²
f) W(x)= x(x²-2)-2(x²-2)
W(X)=(x-2)(x-√2)(x+√2)
g)W(x)=x²(x²-4)+x(x²-4)
W(x)= (x-2)(x+2)(x²+x)
h)W(x)= 5x(x²-3)+(x²-3)
W(x)= 5(x+⅕)(x-√3)(x+√3)
