Answer 3

To expand the expression (c + d)², you can use the formula for squaring a binomial, which is:

(a + b)² = a² + 2ab + b²

In this case, a = c and b = d. Therefore, the expression (c + d)² can be expanded as follows:

(c + d)² = c² + 2cd + d²

So the expanded form of (c + d)² is c² + 2cd + d².
