Answer 3

To find the value of the expression 3x²y - 3xy² - 4x when x = 2 and y = 1, we can substitute these values into the expression and simplify:

3(2)²(1) - 3(2)(1)² - 4(2)

First, let's calculate the values inside the parentheses:

3(2)²(1) = 3(4)(1) = 12 3(2)(1)² = 3(2)(1) = 6 4(2) = 8

Now, substitute the values:

12 - 6 - 8

Next, perform the subtraction:

12 - 6 - 8 = 6 - 8 = -2

Therefore, the value of the expression 3x²y - 3xy² - 4x when x = 2 and y = 1 is -2.
