Factoring+Trinomials

So ya might know me from before. If ya don't, then see me in Double Distribution. So, this page is all about factoring ya trinomials. Scroll down, will ya?

...more, More, MORE!

That's about enough scrollin' now. Okay, so let's say yer in this kinda situation: x² + 9x + 20

So, ya gotch' ya trinomial right up there. If ya wanna learn about how to factor these babies, ya gotta start from the basics, kid.

Step 1: Find all the factors of yer c term (20).

Step 2: That was easy, right, kid? Now ya see which of ya factors add up ta yer b term (9x). ( Don't worry about yer x.)

Step 3: Once ya find those numbers, you' ve found what yer trinomial equals. ((x + 4) (x + 5))

Now will ya do these problems for me?

1.x² + 7x +12 =

2.x² + 9x + 14 =

3.a² + bx + c =
