i did this question before

Answer 2

Answer:

The value of x is 9.

Step-by-step explanation:

Given equation,

$(x+2)^2=a$

If x = 1 is the solution of this equation,

Then it will satisfy the equation,

$\implies (1+2)^2=a$

$\implies (3)^2=a$

$\implies a = 9$

Hence, the value of x is 9 if x = 1 is the solution of the given equation.
