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.
 
oh shit im doing that now, i failed my first test, my teacher is an old men that shaves his head, legs, arms and armpits, hes meesed up
 
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)
