Question

`(x-2)^{2}=100`

Answer 1

x=-8, x=12

Answer 2

12

Answer 3

<=> (x-2) = 10

<=> x = 12

Answer 4

\(\left(x-2\right)^2=100\\ \Rightarrow\left(x-2\right)^2=\left(\pm10\right)^2\)

TH1: x-2=10 ⇒ x=12

TH2: x-2=-10 ⇒ x=-8

Answer 5

(x - 2)² = 100

 x - 2    = 10

      x    = 10 + 2 

      x     = 12 

vậy x =,..

Answer 6

(x-2)^2=100

(x-2)^2=10^2

x-2=10

x-2=-10

x=12

x=-8
