HELP ASAP PLZ As you know, you need to know the first two types of factoring listed above in order to be successful in factoring trinomials of the form ax2 + bx + c.

Part 1:
In your own words, explain how a trinomial of the form 2x2 + 13x + 15 can be turned into a four term polynomial suitable for factoring by grouping. Use complete sentences.

Part 2:
If you were an Algebra 1 instructor and were creating a test on factoring trinomials of the form ax2 + bx + c, what do you think would be the easiest way to create a trinomial that can be factored? Provide one unique example.

What you do is multiply the 2 and the 15, getting 30. Now, you find two numbers that also have a product of 30, but have a sum of 13. Those numbers are 10 and 3.

THANKS 
..HOW U DO PART 2

EXAMPEL

precal · Answer

part one is explaining "factoring by grouping"  you will have to take your middle term and spit it into two terms

anonymous · Answer

Multiply a times c, split it into two numbers, add them together, and make that b.

precal · Answer

part 2 is easy: you can refer to quadratic graphs and look for the functions that cross in 2 places (on the x axis) or in 1 place (on the  x axis).
part 2 is design to test your ability to explain factorable quadratics.  There is no "one" correct solution.
