Try to expand and you will get a linear equation. After that you can solve it by moving terms around and simplifying it.

(x + A)(x + B) = (x + C)(x + D)

~~x~~ + (A + B)x + AB = ^{2}~~x~~ + (C + D)x + CD^{2}

(A + B)x + AB = (C + D)x + CD

(A + B)x - (C + D)x = CD - AB

(A + B - C - D)x = CD - AB

x = ____________________

One step left for you to complete.
