(X-2)x(5-X)=0 ???????????????????????????????????????????????????????????????????????? 08/11/2021 Bởi Madeline (X-2)x(5-X)=0 ????????????????????????????????????????????????????????????????????????
`x(x-2)(5-x)=0` `<=>` \(\left[ \begin{array}{l}x=0\\x-2=0\\5-x=0\end{array} \right.\) `<=>` \(\left[ \begin{array}{l}x=0\\x=2\\x=5\end{array} \right.\) Vậy `x∈{0;2;5}` Bình luận
Đáp án:Giải thích các bước giải: $\text{( x -2 ) ( 5 – x ) = 0 }$ $\left[\begin{array}{ccc}x=0\\x-2=0\\5-x=0\end{array}\right]$ $⇔\left[\begin{array}{ccc}x=0\\x=2\\x=5\end{array}\right]$ $\text{ vậy x ∈ {0 , 2 , 5 }}$ Bình luận
