Bài 2: 

a: \(f\left(x\right)=-9x^3-2x^2+6x-3\)

\(G\left(x\right)=9x^3-6x+53\)

b: \(H\left(x\right)=9x^3-6x+53-9x^3-2x^2+6x-3=-2x^2+50\)

c: Đặt H(x)=0

=>2x²-50=0

=>x=5 hoặc x=-5

a) \(\Rightarrow\left|\dfrac{3}{4}+x\right|=0\Rightarrow\dfrac{3}{4}+x=0\Rightarrow x=-\dfrac{3}{4}\)

b) \(\Rightarrow x+0,4=\dfrac{4}{9}:\dfrac{2}{3}=\dfrac{2}{3}\Rightarrow x=\dfrac{2}{3}-0,4=\dfrac{4}{15}\)

x + 2 = x.2

x + 2 = x + x

x = 2

ta có x+2=x.2

=>x+2=x+x

=>x+x-x=2

=>x=2
