Đáp án:
Giải thích các bước giải:
`(3x-1/2 ) × (5/2-x )=0`
`=>`\(\left[ \begin{array}{l}3x-1/2=0\\5/2-x=0\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}3x=1/2\\x=5/2\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}x=1/6\\x=5/2\end{array} \right.\)
`(3x-1/2 ) × (5/2-x ) = 0`
TH`1 : 3x – 1/2 = 0`
`3x = 0 + 1/2`
`3x = 1/2`
`x = 1/2 : 3`
`x = 1/2 . 1/3`
`x = 1/6`
TH2 : `5/2 – x = 0`
`x = 5/2 + 0`
`x = 5/2`
