Answer 5

I'd suggest you translate this verbal statement into an algebraic one:

"The difference between a number squared and the number" becomes\[x^2-x\]

Now let x=4. Simplify the result, and you'll be done.

Once again: This problem is about representing an unknown quantity (x) algebraically, and then evaluating the expression \[x^2-x\] at a given value (4).
