Question

(x+\(\frac{3}{2}\))\(^2\)=4

 

Answer 1

x=\(\frac{1}{2}\) k nhé!!

Answer 2

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

x          = 2-\(\frac{3}{2}\)

x         =\(\frac{1}{2}\)

Answer 3

đáp án là 7/5 với -13/6 cơ

Answer 4

đặt k=x+\(\frac{3}{5}\)

Answer 5

\(\left(x+\frac{3}{2}\right)^2=4\)

 \(\left(x+\frac{3}{2}\right)^2=2^2\)

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

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

\(x=\frac{1}{2}\)

Answer 6

(x+3/2)^2=4 <=> (x+3/2)^2=(+-2)^2 =>x+3/2=2 hoac x+3/2=-2

=>x=1/2 hoac x=-7/2

Answer 7

\(\left(x+\frac{3}{2}\right)^2=4\Leftrightarrow\left(x+\frac{3}{2}\right)^2=2^2\)

\(\Rightarrow\hept{\begin{cases}x+\frac{3}{2}=2\\x+\frac{3}{2}=-2\end{cases}}\Rightarrow\hept{\begin{cases}x=\frac{1}{2}\\x=\frac{-7}{2}\end{cases}}\)

\(\text{Vậy x}\varepsilon\left\{\frac{1}{2};\frac{-7}{2}\right\}\)
