You can factor this by grouping! We will need to group the trinomial into the expression (k^2 + k)(-2f^2 + f). Now factor from THOSE. k(k + 1)f(-2f + 1).
Since 5 3/5 can be turned into 28/5, then divided by 7/1, you will get 4/5. So Jeremy swims 4/5 of a kilometer each day.
3,500,000 - 2,800,000 = 700,000
So the magazine needs 700,000 readers to meet their goal.
Hope that helps you. :-)
