Final answer:
The value when x = 2 and y = 3 is 6 (option c).
Step-by-step explanation:
The question asks for the value when x = 2 and y = 3.
To find the value, we need to substitute the values of x and y into the given expression.
Substituting x = 2 and y = 3 into the expression, we get:
dx² - y² = 2P(3) = 6P
Therefore, the value when x = 2 and y = 3 is 6 (option c).
