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
Collect the like terms
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.

What is Glucose?</h3>
Glucose is a type of carbohydrate used as a source of energy by living beings, being one of the main nutrients of the cell. This monosaccharide also participates in the formation of complex carbohydrates, such as starch.
Glucose is obtained through food, and its amount in blood (glycemia) is regulated by the action of two hormones that act in the opposite way: insulin and glucagon. Both high and low levels of glucose can be harmful to the body.
