In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
(x - 5)² = 81
x = ?
Step 02:
(x - 5)² = 81
[tex]\begin{gathered} x\text{ - 5 = + }\sqrt[]{81} \\ x1\text{ = 9 + 5 = 14} \end{gathered}[/tex][tex]\begin{gathered} x\text{ - 5 = - }\sqrt[]{81} \\ x2\text{ = - 9 + 5 = }-\text{ 4} \end{gathered}[/tex]
x1 = 14
x2 = - 4
The answer is:
x1 = 14
x2 = -4
