Question

(x -2 ) ^2=36

 

Answer 1

(x-1)= căn bậc 2 của 36

(x-1)=6

x=6+1

x+7

Answer 2

(x-2)^2 = 6^2

x - 2 = 6

x      = 8

Answer 3

\(\left(x-2\right)^2=36\)

⇔ \(\left[{}\begin{matrix}x-2=6\\x-2=-6\end{matrix}\right.\)

⇔ \(\left[{}\begin{matrix}x=8\\x=-4\end{matrix}\right.\)

Answer 4

(x-1)= \(\sqrt{36}\)

(x-1)=6

x=6+1

x+7

Answer 5

(x - 2)²= 36

(x - 2)²= 6²

x - 2    = 6

x         =6 + 2

x         = 8

 

Answer 6

⇔ [x−2=6x−2=−6[x−2=6x−2=−6

⇔ [x=8x=−4[x=8x=−4
