Question

1. Tim x biet:

( x + \(\frac{3}{2}\))² = \(\frac{9}{49}\)

Answer 1

\(\left(x+\frac{3}{2}\right)^2=\frac{9}{49}\)

\(\Rightarrow\left(x+\frac{3}{2}\right)^2=\left(\frac{3}{7}\right)^2\)

\(\Rightarrow x+\frac{3}{2}=\frac{3}{7}\)

\(\Rightarrow x=\frac{3}{7}-\frac{3}{2}\)

\(\Rightarrow x=\frac{-15}{14}\)

Vậy  \(x=\frac{-15}{14}\)

_Chúc bạn học tốt_

Answer 2

(x+3/2)²=9/49

x+3/2=3/7

X=3/7-3/2

x=6-21/14

x=-15/14

Answer 3

\(\left(x+\frac{3}{2}\right)^2=\frac{9}{49}\)

\(\left(x+\frac{3}{2}\right)^2=\frac{3}{7}^2\)

        \(x+\frac{3}{2}=\frac{3}{7}\)

                   \(x=\frac{3}{7}-\frac{3}{2}\)

                   \(x=\frac{6}{14}-\frac{21}{14}\)

                  \(x=\frac{6-21}{14}\)

                 \(x=-15\)

Đúng thì tk nha , sai đừng anti , mơn nhìu !!!
