The expression "twice the difference of two numbers" can be written as 2 times the subtraction of two numbers.
Step 1: Identify the two numbers. Let's call them x and y.
Step 2: Compute their difference. The difference between x and y is represented as (x - y).
Step 3: Multiply their difference by 2 to get "twice the difference". This is represented as 2 * (x - y).
So, the expression representing "twice the difference of two numbers" is 2(x - y).
Therefore, the correct option is 'C' i.e., 2(x - y).
Answer: C) 2(x−y)
