W have the next equation


(x-5)^2\text{ = 3}

Now we are going to solve doing first the square


\begin{gathered} (x-5)^2\text{ = 3} \\ (x-5)^2\text{ - 3 = 0} \\ x^2\text{ - 10x +25 - 3 = 0} \\ x^2\text{ - 10x + 22 = 0} \\ \end{gathered}

The answer for x is:


x\text{ = }5\text{ - }\sqrt[]{3}

and


x\text{ = }5\text{ + }\sqrt[]{3}
