b)x³-0,5x²+4x-2=x²*(x-0,5)+4(x-0,5)=(x²+4)*(x-0,5)
c)-12x³+4x²+9x-3=-4x²*(3x-1)+3*(3x-1)=(-4x²+3)*(3x-1)
d)9x³-9x²+4x-4=9x²*(x-1)+4*(x-1)=(9x²+4)*(x-1)
e)-4x⁴+5x³+12x-15=-4x⁴+12x+5x³-15=-4x*(x³-3)+5*(x³-3)=(-4x+5)*(x³-3)
Mam nadzieję, że dobrze policzyłam:)
x^2(x-2) + 2(x-2)=
(x^2 + 2) (x-2)
b) x^3-0.5x^2+4x-2=
x^2(x-0,5) + 4(x-0,5) =
(x^2 + 4) (x-0,5)
c) -12x^3+4x^2+9x-3=
-4x^2(3x-1) 3(3x-1)=
(-4x^2+3) (3x-1)
d) 9x^3-9x^2+4x-4=
9x^2(x-1) + 4(x-1)=
(9x^2+4) (x-1)
e) -4x^4+5x^3+12x-15=
-x^3(4x-5) + 3(4x-5)=
(-x^3+3) (4x-5)
