The values of the x when the square root is taken on both sides are negative 4 and negative 14.
<h3>What is Algebra?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
The equation is given below.
(x + 9)² = 25
Taking square root on both sides, then we have
(x + 9) = ±5
When the positive sign is considered, then we have
x + 9 = 5
x = -4
When the negative sign is considered, then we have
x + 9 = -5
x = -14
