\(\log_2\left(x^2+3x+2\right)-\log_2\left(3x^2-5x+4\right)=\frac{1}{2}\left(3x^2-5x+4\right)-\frac{1}{2}\left(x^2+3x+2\right)\)
\(\Leftrightarrow\log_2\left(x^2+3x+2\right)+\frac{1}{2}\left(x^2+3x+2\right)=\log_2\left(3x^2-5x+4\right)+\frac{1}{2}\left(3x^2-5x+4\right)\)
Xét hàm \(f\left(t\right)=\log_2t+\frac{1}{2}t\) ...
Đến đây chắc dễ rồi
