Đáp án: \(\left[ \begin{array}{l}x=13/6\\x=-17/6\end{array} \right.\)
Giải thích các bước giải:
|x + $\frac{1}{3}$| - 1 = $\frac{(-3)^2}{6}$
|x + $\frac{1}{3}$| - 1 = $\frac{9}{6}$
|x + $\frac{1}{3}$| - 1 = $\frac{3}{2}$
|x + $\frac{1}{3}$| = $\frac{3}{2}$ + 1
|x + $\frac{1}{3}$| = $\frac{5}{2}$
→ \(\left[ \begin{array}{l}x+1/3=5/2\\x+1/3=-5/2\end{array} \right.\)
→ \(\left[ \begin{array}{l}x=5/2-1/3\\x=-5/2-1/3\end{array} \right.\)
→ \(\left[ \begin{array}{l}x=13/6\\x=-17/6\end{array} \right.\)
