Question

( x- 2/3 ) . (x + 1/4 ) = 0

Answer 1

\(\Rightarrow\hept{\begin{cases}x=\frac{2}{3}\\x=-\frac{1}{4}\end{cases}}\)

Vậy S={2/3;-1/4}

Answer 2

( x- 2/3 ) . (x + 1/4 ) = 0

=> \(\hept{\begin{cases}x-\frac{2}{3}=0\\x+\frac{1}{4}=0\end{cases}}\)

=> \(\hept{\begin{cases}x=\frac{2}{3}\\x=\frac{-1}{4}\end{cases}}\)
