giải ra giùm cái đy chi tiết vô

(2x - 1)² - 3/2 = 3x

<=> 4x² - 4x + 1 - 3/2 - 3x = 0

<=> 4x² - 7x - 1/2 = 0

\(=>x = {7 \pm \sqrt{57} \over 8}\)

\(a,\Rightarrow2x^2-18x-2x^2=0\\ \Rightarrow-18x=0\Rightarrow x=0\\ b,\Rightarrow2x^2-5x-12+x^2-7x+10=3x^2-17x+20\\ \Rightarrow5x=22\Rightarrow x=\dfrac{22}{5}\)

a: \(=\dfrac{\left(3x-1\right)^3}{3x-1}\cdot\dfrac{8xy}{12x^3}=\dfrac{2y\left(3x-1\right)^2}{3x^2}\)

b: \(=\dfrac{\left(x-5\right)\left(x+5\right)}{x\left(x-5\right)}=\dfrac{x+5}{x}\)
