Question

hello factoring how do you do it this is a math website to help right not ignore ?

Answer 1

davette im lagging, and no need to accuse us. Have I not helped u?

Answer 2

oh and i am helpin someone at the moment..

Answer 3

and we're all volunteers

Answer 4

ill let elizated do this one.

Answer 5

i kno dat but i been poseted dis up and like no one answered and i need to finishh dis before school start bck

Answer 6

well factoring is pretty simple. i will show you the basic way to factor. if an equation cannot be factored, use the quadratic formula.
ok so your standard equation for factoring is Ax^2 + Bx + C
First, multiply A x C. Now find two numbers where the sum of the numbers is B, and the product is AC. We will call these two numbers Z and Y.
Now insert Zx + Yx into the equation.
Ax^2+ Zx +Yx + C
From here, you can use grouping. Example below:
9a^2-12a+4
9 x 4=36
the factors are -6 and -6
9a^2 -6a -6a +4
now group using greatest common factor.
3a(2a-2) -3(a-2)
(3a-3)(2a-2) is your final factored answer.

Answer 7

ok

Answer 8

if you need me to explain more i can :) factoring is my strong suit.

Answer 9

ok

Answer 10

so... is that a yes explain more or...?

Answer 11

yes explian more and do u mind me giving u a problem to help me on and then u help me go through it step by step??

Answer 12

sure! post away

Answer 13

9x^2-8y^2

Answer 14

so what is the very first thing i do?

Answer 15

ok we are going to look at this as 9x^2+ 0xy -8y^2
so first multiply 9 and 8 to get 72.

Answer 16

unfortunately, 72 is not a square, so no factors of 72 will add together to give you 0. this makes this equation prime and unfactorable.

Answer 17

ok soit means its a prime??

Answer 18

yup. this is correct, indeed!

Answer 19

Another medal for u two!

Answer 20

ok

Answer 21

yay! :D thank you bahrom!

Answer 22

Factor x^2 - 16y^2
how bout this one??

Answer 23

it would be 8 and two??

Answer 24

same thing. x^2 -16y^2 can be written as x^2 +0xy -16y^2
so factors of 16 that equal 0? 4 and -4.
now we can go back and substitute those for 0xy, but in this case you can use the shortcut and just go directly to (x+4y)(x-4y) because there is not coefficiant in front of the x^2. (besides the 1)

Answer 25

woha dis is so confusing

Answer 26

haha sorry... it probably looks better on paper when you write it in collumns.

Answer 27

its ok its just that da whole lesson is just plain confusing

Answer 28

well just keep setting it up the way i showed you. it works for every problem even if its not the easiest way to get there, you won't have to memoriz a bunch of crap.

Answer 29

ok
