<h3>
Answer: Choice C. (2x - 6i)(x + 3i)</h3>
Work Shown:
2x^2 + 18
2(x^2 + 9)
2(x - 3i)(x + 3i) .... see note below
(2x - 6i)(x + 3i)
Note: I used the rule that a^2 + b^2 = (a - bi)(a + bi). I recommend FOILing out the right hand side to confirm the equation is true. You'll use the idea that i^2 = -1.

<h2>
The product of two numbers is <em>
a,</em>
of both numbers.</h2>
Step-by-step explanation:
Given,
The product of two numbers = a
To find, the both numbers = ?
Let the two numbers = x
∴ x × x = a
⇒ 
= a
⇒ 
Comparing the powers, we get
⇒ x =
∴ First number = and Second number =
Thus, the product of two numbers is <em>a,</em> of both numbers.
