can someone check me and see if this is correct.

ã(4x+1) + 3 = 0

ã(4x+1)= -3

ã(4x+1).2= -3.2

4x + 1 = 9

4x = 9 - 1

4x = 8

x = -2

not sure what your symbol ã means but it appears like you mean square root.

If that is the case then in your second line

√(4x+1)= -3 you could stop, since by definition the square root symbol says to take the positive square root of a number.

So it could not be a negative.

Your solution would be:

No solution in the real number set
