What two numbers can you multiply together to make 28 and add up to 4?

texmechanica · Answer

Can you just show me how to factor?

anonymous · Answer

Break 28 up into its prime factors and you should see it. I won't solve it for you because you need to know how to do it yourself. I'll help you.

anonymous · Answer

If you break the last term up into its prime factors you should be able to find a combination of those factors that when multiplied together equal the last term and when added together equal the middle term.

2 * 2 * 7 = 28
4 * 7 = 28
7-4=3
