Or with re-arranging:
The negative at the front is not comfortable foe factorising. Divide it out as a common factor. All the signs will change.
The factors of a quadratic trinomial are two brackets.
The top row gives the first bracket and the bottom row gives the second bracket:
You could also solve the sign issue by re-arranging the terms:

To factor the quadratic expression (-5k^2 - 22k + 15), you can use the factoring by grouping method. First, multiply the leading coefficient (-5) by the constant term (15), resulting in (-5 \times 15 = -75). Next, find two numbers that multiply to (-75) and add to the coefficient of the linear term (-22). These numbers are (-25) and (3). Rewrite the middle term (22k) using these numbers, resulting in (-5k^2 - 25k + 3k + 15). Group the terms, factor by grouping, and then factor out the greatest common factor from each pair of terms. This will yield the factored form of the quadratic expression.

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.
