POMOCY!!! Jak rozłożyć to na czynniki???
y^3-8+6y^2-12yx^5-x^3-x^2+18z^4+125z
Jak rozłożyć to na czynniki?
y³-8+6y²-12y=(y³-2³)+6y(y-2)=(y-2)(y²+2y+4)+6y(y-2)=(y-2)(y²+2y+4+6y)=(y-2)(y²+8y+4)x⁵-x³-x²+1=x³(x²-1)-(x²-1)=(x³-1)(x²-1)=(x³-1³)(x-1)(x+1)=(x-1)(x²+x+1)(x-1)(x+1)8z⁴+125z=z(8z³+125)=z[(2z)³+5³]=z[(2z+5)(4z²+10z+25)]

Jak rozłożyć to na czynniki?
y³-8+6y²-12y=(y³-2³)+6y(y-2)=(y-2)(y²+2y+4)+6y(y-2)=(y-2)(y²+2y+4+6y)=(y-2)(y²+8y+4)
x⁵-x³-x²+1=x³(x²-1)-(x²-1)=(x³-1)(x²-1)=(x³-1³)(x-1)(x+1)=(x-1)(x²+x+1)(x-1)(x+1)
8z⁴+125z=z(8z³+125)=z[(2z)³+5³]=z[(2z+5)(4z²+10z+25)]
