%28A%2BB%29%5E2%2F%28C%2BD%29%5E2=%2822B-300%29%2F4CD

%28A%2BB%29%5E2=%28C%2BD%29%5E2%2822B-300%29%2F4CD Multiply both sides by %28C%2BD%29%5E2


A%2BB=0%2B-sqrt%28%28C%2BD%29%5E2%2822B-300%29%2F4CD%29 Take the square root of both sides


A=0%2B-sqrt%28%28C%2BD%29%5E2%2822B-300%29%2F4CD%29-B Subtract B from both sides
