\(x^3+2x^2\left(4y-1\right)-4xy^2-9y^3-f\left(x\right)=-5x^3+8x^2y-4xy^2-9y^3\\ \Rightarrow\left(x^3+8x^2y+2x^2-4xy^2-9y^3\right)-f\left(x\right)=-5x^3+8x^2y-4xy^2-9y^3\\ \Rightarrow f\left(x\right)=x^3+8x^2y+2x^2-4xy^2-9y^3+5x^3-8x^2y+4xy^2+9y^3\\ \Rightarrow f\left(x\right)=6x^3+2x^2\)

= (1 - 3) + (5 - 7) + ... + (2001 -2003) + 2005
= - 2 nhân 501 + 2005
= -1002 + 2005 = 1003
Đáp án là: 1003 nha!

Ta có: Om là phân giác của góc xOy
=>\(\widehat{yOm}=\dfrac{\widehat{xOy}}{2}\)
On là phân giác của góc yOz
=>\(\widehat{yOn}=\dfrac{\widehat{yOz}}{2}\)
\(\widehat{mOn}=\widehat{yOm}+\widehat{yOn}=\dfrac{\widehat{xOy}}{2}+\dfrac{\widehat{yOz}}{2}=\dfrac{180^0}{2}=90^0\)
=>Om\(\perp\)On
