[ Explanation ]
- Simplify:
------------------------------------------
- Apply Perfect Square Formula (
= 
+ 2ab + 
) a = 5x, b = 2
+ 2 · 5x · 2 + 
: 
+ 20x + 4
+ 20x + 4
![\boxed{[ \ Eclipsed \ ]}](https://tex.z-dn.net/?f=%5Cboxed%7B%5B%20%5C%20Eclipsed%20%5C%20%5D%7D)
4x+16=-2
Subtract 16 from both sides
4x=-18
Divide both sides by 4
x=-18/4
x= -9/2
Final answer: x=-9/2
