Answer:
4 or 5 or even 6
Step-by-step explanation:
1 ounce = 0,0625 pound = 1/16 pound
10-oz = 0,625 pounds = 1/16 * 10 = 10/16 = 5/8 pounds
3 * 5 (bags donated to the pantry) = 15
15 ÷ 5/8 = = 15 * 8/5 = 3 * 8 = 24
Answer: There are 24 10-oz bags needed to fit three 5-lb bags.
The function is already factored, so it equals zero if and only if one of its factors equals zero:

or

Since -2 is smaller than -3/2 the solutions are -2 and -3/2
