Solving a radical equation

How do you solve this one?
√(x + 1) = √(5x + 4)

---

√(x + 1) = √5x + 4)
x + 1 = 5x + 4   {squared each side of the equation, removing the radical signs}
1 = 4x + 4   {subtracted x from each side}
-3 = 4x   {subtracted 4 from each side}
x = -3/4   {divided each side by 4}
