First subtract 2 from both sides: √x − 3 = 4. Now that the square root is isolated, we can square both sides of the equation: (√x − 3)2 = 42. Since the square and the square root cancel we get: x − 3 = 16.

There are 2 cases: Case 1: x is negative (x < 0) Since LHS is always non negative (it is the principal square root so it is never negative) so this inequality will hold for all values of x. But since under the square root, we cannot have a negative value, (x + 2) >= 0. x >= -2. Case 2: phoenix baseball camps
