To simplify the expression (3x (x -1) - 4 (x^2 - x)), first distribute the terms:
(3x \times x - 3x \times 1 - 4 \times x^2 + 4 \times x)
(= 3x^2 - 3x - 4x^2 + 4x)
Next, combine like terms:
(3x^2 - 4x^2 - 3x + 4x)
(= -x^2 + x)
So, the simplified expression is (-x^2 + x).

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.
