Final answer:

The value of the expression x²-4(x-y) for x=8 and y=3 is 44 after substituting the values and simplifying the expression.

Step-by-step explanation:

To evaluate the expression x²-4(x-y) for x=8 and y=3, we simply substitute the provided values into the expression and simplify.

First, replace x with 8 and y with 3:

(8)² - 4(8 - 3)

Now we calculate the square of 8 and the expression in the parenthesis:

64 - 4(5)

Multiply 4 by 5:

64 - 20

Finally, subtract 20 from 64:

44
