x=-b(+,-)(square root of...)b^2-4(a)(c)
Divided by 2(a)

Quadratic formula.

or if you want to do it the trial an error way, get the t and k to have a sum of B and a product of C

I get what your talking about
you gotta make the factoring squares.
so like

.|3x..|-8
X|3x^2|-8x
-|
3|-9x|-27

Or just go on www.hotmath.com and it will explain everything perfect with the problems right from your book.

Partial Fraction decomposition is what you're thinking of, and no, that's not it.

Answer:

You have Ax2+bx+c
Find two numbers (we'll say f and t) that when multiplied together equal the same thing as A times C, AND those original two numbers (f,t) have to equal b when added together.
Then:
replace bx with f and t (but still with the x part)
So you have:
Ax2+fx+tx+c
Then:
(Ax2+fx)+(tx+c)
Then:
Out of each of those parenthases you need to factor out a common number so both parenthasis look the same. Example: if you have (4x^2+2x)+(6x+3), you can take a 2x out of the first parenthases and a 3 out of the second, and then they will both be the same:
2x(2x+1)+3(2x+1).
Then:
Combine the terms outside the parenthasis and combine the two parenthases that are the same into one:
(2x+3)
