Question

(X-1)^2₌₂₅

Answer 1

\(\Rightarrow\orbr{\begin{cases}\left(x-1\right)^2=5^2\\\left(x-1\right)^2=\left(-5\right)^2\end{cases}}\)

\(\Rightarrow\orbr{\begin{cases}x-1=5\\x-1=\left(-5\right)\end{cases}}\Rightarrow\orbr{\begin{cases}x=6\\x=\left(-4\right)\end{cases}}\)

Answer 2

(x - 1)^2 = 5^2

=> x - 1 = 5

x = 5 + 1

x = 6
