Đáp án + Giải thích các bước giải:
`c//(2x+3)(3x-6)=0`
`⇔` \(\left[ \begin{array}{l}2x+3=0\\ 3x-6=0\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}2x=-3\\ 3x=6\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x=-\frac{3}{2}\\ x=2\end{array} \right.\)
Vậy `S={-(3)/(2);2}`
`d//(0,5x-4)(2x-5)=0`
`⇔` \(\left[ \begin{array}{l}0,5x-4=0\\2x-5=0\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}0,5x=4\\2x=5\end{array} \right.\)
`⇔` \(\left[ \begin{array}{l}x=8\\x=\frac{5}{2}\end{array} \right.\)
Vậy `S={8;(5)/(2)}`
