it would work it would just expand (c^(1/2) + d^(1/2))^2

(a+b)^8 = (a+b)(a+b)(a+b).....(a+b) up to 8 times. Expanding all that is a pain. So, some math geeks created an approach to memorize the pattern for any power. In this case, it gets nastily BIG in terms of the ultimate expression.

c^4 + 8c^7/2*d^1/2 + 28c^3*d + 56c^5/2*d^3/2 + 70c^2*d^2 + 56c^3/2*d^5/2 + 28c*d^3 + 8c^1/2*d^7/2 + d^4
