To combine (5a + 9b) - (2a + 4b), we distribute the negative sign inside the parentheses to both terms inside the second set of parentheses, which gives us 5a + 9b - 2a - 4b. Then, we combine like terms, which are the terms with the same variable and exponent. This yields (5a - 2a) + (9b - 4b), which simplifies to 3a + 5b. Therefore, the combined expression is 3a + 5b.

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.
