Toán giải phương trình sau: (x+7)(x+6/2-4x/3)=0 23/10/2021 By Melody giải phương trình sau: (x+7)(x+6/2-4x/3)=0
`\text{~~Holi~~}` `(x+7)((x+6)/2-(4x)/3)=0` `->`\(\left[ \begin{array}{l}x+7=0\\\dfrac{x+6}{2}-\dfrac{4x}{3}=0\end{array} \right.\) `->`\(\left[ \begin{array}{l}x=-7\\x=\dfrac{18}{5}\end{array} \right.\) Vậy `S={-7;18/5}` Trả lời

`\text{~~Holi~~}`
`(x+7)((x+6)/2-(4x)/3)=0`
`->`\(\left[ \begin{array}{l}x+7=0\\\dfrac{x+6}{2}-\dfrac{4x}{3}=0\end{array} \right.\)
`->`\(\left[ \begin{array}{l}x=-7\\x=\dfrac{18}{5}\end{array} \right.\)
Vậy `S={-7;18/5}`
