Please be correct, HELP ASAP!!!!

Answer 1

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

Step-by-step 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,

$\displaystyle \: a = \pm \sqrt{b}$

by that

$\displaystyle \: x + 15 = \pm\sqrt{10}$

cancel 15 from both sides:

$\displaystyle \: x = \pm\sqrt{10} - 15$

so

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