Given the following question:


(x-25)^2=36

To find the answer we are going to have to use inverse of operations to isolate the variable.


\begin{gathered} (x-25)^2=36 \\ (x-25)^2=36=x-25=\sqrt[]{36} \\ x-25=\sqrt[]{36} \\ -25+25=0 \\ \sqrt[]{36}=6=6*6 \\ 6+26=31 \\ x=31 \\ x-25=-\sqrt[]{36} \\ -\sqrt[]{36}=6i \\ x-25=6i \\ -25+25=0 \\ 6i+25=19 \\ x=19 \\ x=31 \end{gathered}

Your two solutions are "x = 19, and x = 31."
