i did this question before

Answer:

The value of x is 9.

Step-by-step explanation:

Given equation,

[tex](x+2)^2=a[/tex]

If x = 1 is the solution of this equation,

Then it will satisfy the equation,

[tex]\implies (1+2)^2=a[/tex]

[tex]\implies (3)^2=a[/tex]

[tex]\implies a = 9[/tex]

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