Answer:
(x+2) ^2 =11
Step-by-step explanation:
x^2+4x=7
To complete the square, take the coefficient of the x term, 4
Then divide by 2, 4/2 =2
Then square it 2^2 =4
Add that to both sides
x^2 +4x+4 = 7+4
The left hand side can be rewritten as (x+b/2) ^2 where b is the coefficient of the x term
(x+2) ^2 =11
