Question

(x-1)^2=25

Answer 1

(x-1)²=25

(x-1)²=5²

=> x-1=5

=> x=6

Answer 2

(x-1)²=25

=> (x-1)²=5²

=> x-1=5

=> x=5+1

=> x= 6

Vậy x= 6

Answer 3

(x-1) mũ 2=5 mũ 2

x-1=5

x=6

Answer 4

\(\left(x-1\right)^2=25\)

\(\Rightarrow x-1=\pm5\)

+) \(x-1=5\Rightarrow x=6\)

+) \(x-1=-5\Rightarrow x=-4\)

Vậy \(x\in\left\{6;-4\right\}\)

Answer 5

(x-1)\(^2\)=25

(x-1)\(^2\)=5\(^2\)

x-1=5

x=5+1

x=6

Answer 6

(x-1)\(^2\)=25

\(\Rightarrow\)x-1=+5

+)x-1=5\(\Rightarrow\)x=6

+)x-1=-5\(\Rightarrow\)x=-4

vậy x\(\in\){6;-4}
