Complete question:
<em>What values of c and d would make the following expression represent a real number? i(2 + 3i)(c + di)
</em>
<em>choices: A)c = 2, d = 3 B)c = –2, d = 3 C)c = 3, d = –2 D)c = –3, d = –2</em>
<em />
<em>Option D</em><em> is correct. </em> The value of c and d for the expression to be real are -3 and -2 respectively
Given the expression
Expand the expression

For the resulting function to be real, then the imaginary part must be zero i.e.
If d = -2, then;
Hence the value of c and d for the expression to be real are -3 and -2 respectively.
