There is NO SOLUTION.
sqrt(4x + 1) + 3 = 0
sqrt(4x + 1) = -3
A square root cannot be a negative number, so there is no solution.

If you tell us what part you are taking the square root of, it would be helpful.
Is it sqrt(4x + 1) + 3 = 0?
If so, it has no real solution.

um i think u mean square root (4x+1) +3=0
so sub. 3 from both sides.
sqrt. (4x+1) = -3
then square both sides.
4x+1=9
sub. 1
4x=8
so x=2
