No solution

Step-by-step explanation

We want to find the number of solutions for


√(2x + 3) + 6 = 0

Add -6 to both sides.


√(2x + 3) = - 6

Square both sides


2x + 3 = 36

Solve for x.


2x = 36 - 3


2x = 33


x = (33)/(2)


x = 16.5

Substitute back into the equation.


\sqrt{2((33)/(2))+ 3} + 6 = 0


√(33+ 3) + 6 = 0


√(36) + 6 = 0


6+ 6 = 0


12 = 0

This is not true.

The equation has no solution
