x2-7x-44 (x-11)(x+4)
That's not a trinomial, but it factors to x(x + 19)
(x + 3)(x - 2)
x2 + 18x - 50 does not have rational factors.
just make the trinomial easier to factor. ex -x2 + 3x + 4 ... most books don't teach you how to factor when a leading term is negative. ... so -1(x2- 3x- 4) ... now factor again ignoring the -1 -1(x - 4)(x + 1)
