Please be correct, HELP ASAP!!!!

Answer 1

`\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`
