Math factoring

[backyardbooter]

all i need is liek a checklist of steps to go through for the ones with x2 and for ones like 4x2

thanks

 

[backyardbooter]

k that is a little unclear never mind the x2 part

just what are the steps for factroing from ax2+bx+c form to a(x-t) (x-k) form

 

[Natasha]

is it called decomposition or something?? because i think i know how to do that..

 

[backyardbooter]

yes

 

[GingerKid08]

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

Divided by 2(a)

Quadratic formula.

 

[backyardbooter]

quadratic formula gives me the roots or zeroes i want to put standard from into factored form

 

[Leckett]

^thats it.

[Leckett]

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

 

[GingerKid08]

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.

yea man, all i have is some cool program on my calculator and alls i have to do is put in a, b and c and it solves it

MATH SUCKS

 

[Alexander_Keith]

goddamn.. i had forgotten grade 10 factoring... math starting thursday is gonna suck

 

[Gnarshred]

dude, its gonna be either reverse foil or factor by grouping.

i dont feel like teaching you tho.

 

[chapz]

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

 

[skogenjake]

factoring is the worst part of math go in after school for help

 

[freeskier_1080*]

just read page 304 and then go to page 308 and do #7 and then yur all good for the exam.

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)

What the hell? Half my reply got cut off and I'm not going to rewrite all that shit

this might help, I made it last year and have no idea whats going on.
