F(x)= 99x \(98x^2+97x^3+96x^4+...+2x^{98}+x^{99}+1\)

G(x)=1+x-\(x^2-x^3+x^4+x^5-x^6-x^7+x^8+...+x^{100}\)

Tính F(1) + G(-1)

Tính F(x) + G(x)

Cho A= \(\dfrac{1}{2015}+\dfrac{2}{2016}+...+\dfrac{2016}{4030}-2016\)

B=\(\dfrac{1}{2015}+\dfrac{1}{2016}+...+\dfrac{1}{4030}\)

CMR \(\dfrac{A}{B}\)\(\varepsilon\)Z

Tìm x biết:

\(\left|x-2015\right|^{2016}\left|x-2016\right|^{2015}=1\)

Có f(x) + 2f(2-x) = x + 2 với mọi x.

Tính f(-1)

Tìm x y thuộc Z biết

\(\left(x+y\right)^2=\left(x-1\right)\left(y-1\right)\)

Cho\(\dfrac{2x-3y}{5}=\dfrac{5y-2z}{3}=\dfrac{3z-5x}{2}\)

Tính\(\dfrac{12x+5y-3z}{x-3y+2z}\) với x,y,z\(\ne\)0

Giúp mik nha mn!!!
