To FOIL the expression (5x - x^2)(5x - x^2), follow these steps:

Multiply the First terms: (5x * 5x) = 25x^2
Multiply the Outer terms: (5x * -x^2) = -5x^3
Multiply the Inner terms: (-x^2 * 5x) = -5x^3
Multiply the Last terms: (-x^2 * -x^2) = x^4

Combine like terms:

25x^2 - 5x^3 - 5x^3 + x^4

Combine like terms:

25x^2 - 10x^3 + x^4

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
