Question 977061: Expand (sq rt c + sq rd d)^2 and simplify. Assume c> or equal to 0 and d > or equal to 0
b. c+2 sqft cd + d
c. c^2-d^2
d. c^2+2cd_d^2
I thought it was [c]+2[cd]+[d] but I was wrong.
Thank you

It's B.
sqrt%28c%29 squares to be just C
sqrt%28d%29 squares to be just D
And the inner term remains a radical.
