Lim [ 2x + 1 / 2 - √4x + 6 ]
x→-1/2

Lim [ (2x + 1)(2 + √4x + 6)
x→-1/2 .. / (2 - √4x + 6)(2 + √4x + 6) ]

Lim (2x + 1)(2 + √4x + 6)
x→-1/2 .. / (4 - (4x + 6)

Lim (2x + 1)(2 + √4x + 6)
x→-1/2 .. / (4 - 4x - 6)

Lim (2x + 1)(2 + √4x + 6)
x→-1/2 .. / (-4x - 2)

Lim (2x + 1)(2 + √4x + 6)
x→-1/2 .. / -2 (2x + 1)

Lim (2 + √4x + 6)
x→-1/2 .. / -2

= 2 + √4(-1/2) + 6 / -2

= 2 + √-2 + 6 / - 2

= 2 + √4 / -2

= 2 + 2 / -2

= 4/ - 2

= -2
