The original problem was:

---
step 1 multiply by the common denominator of (a+2). We get

---
step 2 - distribute and get x^2 on one side = 0.

---
step 3 - solve for x by factoring:

X = 4 and x = -2.
However, look back at our denominator. We have a restriction @ x = -2. we cannot use x = -2, So, the only answer is x = 4.
