\(TH_2:3x+18=0\)

\(\Leftrightarrow3\left(x+6\right)=0\)

\(\Leftrightarrow x+6=0\)

\(\Leftrightarrow x=-6\)

Vậy pt có tập nghiệm \(S=\left\{-6;8\right\}\)

\(\left(x+2\right)\left(3x-24\right)-12\left(8-x\right)=0\)

\(\Leftrightarrow3\left(x+2\right)\left(x-8\right)+12\left(x-8\right)=0\)

\(\Leftrightarrow\left(x-8\right)\left(3x+18\right)=0\)

\(TH_1:x-8=0\)

\(\Leftrightarrow x=8\)

\(TH_2:3x-18=0\)

\(\Leftrightarrow3\left(x-6\right)=0\)

\(\Leftrightarrow x-6=0\)

\(\Leftrightarrow x=6\)

Vậy pt có tập nghiệm \(S=\left\{6;8\right\}\)

(x-1)² +2(x-1)(x+2) + (x+2)²=0

<=> (2x+1)²=0

<=> 2x+1=0

<=> 2x= -1

<=> \(x=-\dfrac{1}{2}\)

Vậy .....
