Tìm x: \(3\left(x-2\right)^2-1\frac{1}{4}\left(1+3x\right)^2=1\frac{1}{3}\left(x-1\right)\left(3-x\right)-1\frac{1}{6}x\left(x-3\right)\)
Tìm x: \(\frac{\left(x-2\right)^2}{2}-4\frac{1}{3}\left(x+3\right)^2=\frac{1}{4}\left(x-1\right)\left(x-2\right)-2\left(3x-1\right)\left(2+3x\right)\)
Tìm x: \(\frac{\left(2-3x\right)^2}{3}-\frac{\left(1+2x\right)^2}{2}=\frac{3}{4}-2\left(x-1\right)\left(x+2\right)+x\left(1+x\right)\)
Tìm x: \(\frac{\left(x-3\right)^2}{3}-\frac{\left(2x+1\right)\left(1-3x\right)}{2}=\frac{x\left(x+2\right)}{3}-\left(1+x\right)^2\)
Tìm x: \(\frac{\left(2x-1\right)^2}{3}-\frac{1}{2}\left(1+3x\right)^2=\frac{1}{3}\left(x-1\right)\left(2-3x\right)\)
Tìm x: \(\left|x-5\right|+\frac{\left(x-1\right)\left(x-3\right)}{2}=\frac{\left(x+1\right)^2}{3}-\frac{\left(1-2x\right)^2}{4}\)
