Question

What is the solution of sqrt x + 2 - 15 = -3?

a. x = 142
b. x = 232
c. x = 322
d. no solution

Answer 1

√(x+2) -15 = -3
√(x+2)=12
x+2=144
x=142 option a

Answer 2

`x=142`

Explanation:

The given equation is:

`√(x+2)-15=-3`

Adding 15 on both the sides, we get

`√(x+2)-15+15=-3+15`

`√(x+2)=12`

Squaring on both the sides of the equations, we have

`x+2=144`

Subtracting 2 on both the sides, we get

`x+2-2=144-2`

`x=142`

Thus, the solution of the given equation is
`x=142`.

Hence, option A is correct.
