Answer: D. 2
Explanation:
We will create a mathematical equation and then solve it to solve for the integer. Let x be the "nonzero integer." The word product represents multiplication.
Given:
x * 2 = x²
Multiply:
2x = x²
Move all terms to one side of the equation:
x² - 2x = 0
Factor:
(x - 2)(x) = 0
Solve:
x = 2, 0
Since this term is a nonzero integer, this rules out answer 0, leaving us with D. 2.
