[5s online]

Tim x biet 

(x+1)^2=4/9

Answer 1

[Đinh Tuấn Việt]

(x + 1)² = \(\frac{4}{9}\)

=> x + 1 = \(\frac{2}{3}\)hoặc x + 1 = \(-\frac{2}{3}\)

=> x = \(\frac{-1}{3}\) hoặc x = \(-\frac{5}{3}\)

Answer 2

[thien ty tfboys]

\(\left(x+1\right)^2=\frac{4}{9}\Rightarrow\left(x+1\right)^2=\left(+-\frac{2}{3}\right)\)

\(\Rightarrow x+1=\frac{2}{3}\) hoac \(x+1=-\frac{2}{3}\Rightarrow x=-\frac{1}{3}\) hoac \(x=-\frac{5}{3}\)
