Answer 11

For 3y^2+5y-2:

You need to find what two terms when multiplied together will give you 3y^2.
Then find what two terms when multiplied together will give you a -2.
Once you find these terms, then the real test is determining the middle term which will come from the above terms.

You can try working this out with the rules given and see how it works.

Answer 12

Answer 13

What two factors (terms) will give you 3y^2?
