3 or −7. 
This equation is solved by taking the number infront of x (in this case an invisible 1) and the last number (4) and multiplying

4

then split that up so that the two numbers equal the middle number when added and the last number when multiplies

2 and 2

now use the Double Bubbles

(x + 2) (x + 2)

This may be re-written as (x+2)2=25.

So x+2=±5.

So x=3 or −7.
