Question

4𝑥 − 8 + 3𝑥(𝑥 − 2) = 0

Answer 1

\(\Leftrightarrow4\left(x-2\right)+3x\left(x-2\right)=0\\ \Leftrightarrow\left(3x+4\right)\left(x-2\right)=0\\ \Leftrightarrow\left[{}\begin{matrix}x=-\dfrac{4}{3}\\x=2\end{matrix}\right.\)

Answer 2

4(x-2)+3x(x-2)=0

(x-2)(4+3x)=0

x=2 hoặc x=-4/3

Answer 3

`4x-8+3x(x-2)=0`

`=>4(x-2)+3x(x-2)=0`

`=>(x-2)(3x+4)=0`

`=>`$\left[\begin{matrix} x-2=01\\ 3x+4=0\end{matrix}\right.$

`=>`$\left[\begin{matrix} x=2\\ x=-\dfrac{4}{3}\end{matrix}\right.$
