Suppose that Oscar and Felix are roommates and they want to find a way to divide up household chores—cooking meals and doing laundry. It takes Oscar 45 minutes to make a meal and 90 minutes to do a load of laundry. It takes Felix 60 minutes to make a meal and 60 minutes to do a load of laundry.

Oscar should be doing the cooking and Felix should be doing the laundry.

Step-by-step explanation:

It takes Oscar 45 minutes to make a meal and 90 minutes to do a load of laundry.

On the other hand, it takes Felix 60 minutes to make a meal and 60 minutes to do a load of laundry.

Comparing the time taken for each to make a meal, Oscar uses lesser time, so he should be doing the cooking because he does it faster.

Also, comparing the time taken for each to do a load of laundry, Felix uses lesser time, so he should be doing the laundry because he does it faster.

quartic functions has x = –1 and x = –2 as its only two real zeroes:

f(x) = a(x+2)(x+1)   a: real number
