Question

Which one is correct?

Answer 1

`(x+4)^2=4`

Explanation:

`x^2+8x+12=0\\</p><p>\implies (x^2+8x+16)+12=16\\</p><p>\implies (x+4)^2=16-12\\</p><p>\implies \boxed{(x+4)^2=4}`

Answer 2

(x +4)^2 = 4

Explanation:

if we add 4 to the expression x^2 + 8x + 12 we will have a perfect square which is shown as (x +4)^2

so (x +4)^2 = 4 is equivalent to the expression x^2 + 8x + 12
