\displaystyle \: x_{ \text{lesser}}= - 18.16\\ x _{ \text{greater}} = - 11.84

Explanation:

we are given a equation

we want to figure out x

add 10 to both sides:


\displaystyle \: (x + 15 {)}^(2) = 10

square root both sides:

remember that,


\displaystyle \: a = \pm √(b)

by that


\displaystyle \: x + 15 = \pm√(10)

cancel 15 from both sides:


\displaystyle \: x = \pm√(10) - 15

so


\displaystyle \: x_{ \text{lesser}}= - 18.16\\ x _{ \text{greater}} = - 11.84
