#1**0 **

Solve for x:

sqrt(x + 4) = x - 2

Raise both sides to the power of two:

x + 4 = (x - 2)^2

Expand out terms of the right hand side:

x + 4 = x^2 - 4 x + 4

Subtract x^2 - 4 x + 4 from both sides:

5 x - x^2 = 0

Factor x and constant terms from the left hand side:

-x (x - 5) = 0

Multiply both sides by -1:

x (x - 5) = 0

Split into two equations:

x - 5 = 0 or x = 0

Add 5 to both sides:

x = 5 or x = 0

So, x = 0 discard. **Or x = 5**
