Question

Factoring... Yay... :)

Answer 1

First things first, do you want to.... explain this format?
I don't do factoring like.....-that- lol

Answer 2

oh

Answer 3

its tic tac toe method

Answer 4

wat is that-

Answer 5

the fromula is ax^2 + bx + c

Answer 6

top left is a
top middle is c
top right is a*c

Answer 7

middle right is a factor of a*c that adds up with the other factor to equal b

Answer 8

@AZ @angle
i've never done something called the 'tic-tac-toe method'

Answer 9

bottom right is the other factor

Answer 10

do you have to factor this way-

Answer 11

thats how i was tought

Answer 12

damn, they dipped

Answer 13

im open to more methods

Answer 14

sorry, had to go delete a spam post

I've never learned this before but it seems similar to factoring by grouping

Answer 15

yes

Answer 16

ill make a template

Answer 17

so the arrow shows which way the rows multiply

Answer 18

a is in square 1-1

Answer 19

c square 1-2

Answer 20

a*c in square 1-3

Answer 21

now square 2-3 and 3-3 are factors of a*c that add up to b

Answer 22

once you put those there, square 2-1 * 2-2 = 2-3

Answer 23

same with row 3

Answer 24

then 3-1 * 2-1 = 1-1

Answer 25

as with column 2

Answer 26

Let me try an example and you tell me if I'm understanding your method correctly:

If I had an equation: 2x^2 - x - 3
a = 2
b = -1
c = -3

Then my box would look like:

Answer 27

so, instead of -6 and 1, you would do -3 and 2 cuz -3 + 2 = -1, b

Answer 28

Are you required to use this method? ;-;

Answer 29

no

Answer 30

good, let's try factoring by grouping instead :D

Answer 31

which problem do you want to try first?

Answer 32

any
also, this would be ur problem

Answer 33

6. Factor 2x4−13x2−45
2x^4−13x^2−45
=(2x^2+5)(x+3)(x−3)

Answer 34

ohh I wasn't too far off, that would make sense

Answer 35

mhm, u did good

Answer 36

better than i did my first

Answer 37

kynxkatz, howd u get that?

Answer 38

Solved it?

Answer 39

yea

Answer 40

N just call me Kynx

Answer 41

That’s my first name

Answer 42

ight

Answer 43

Since katz is so eager to try out number 6, let's take a look at how that would look in one of your boxes
2x^4−13x^2−45

Answer 44

Imma go through the questions n solve them

Answer 45

Wait wht

Answer 46

correct Angle

Answer 47

When did i give direct answers

Oh it u, thought it was sumone else

Answer 50

so u would make 2x^4 - 13x^2 - 45 2u^2 - 13u - 45 | u=x^2

Answer 51

that allows u to make the table

Answer 52

I dont even have to strength to argue wit u, I’m just here to help ppl

Answer 53

7. Since both terms are perfect cubes, factor using the difference of cubes formula,
a^3-b^3= =
a^3-b^3=(a-b)(a^2+ab+b^2) where a=4x a=4x and b=1b=1
(4x−1)(16x^2+4x+1)

Answer 54

Srry that took so long i just got out of chemo like 1 hr ago so I’m just kinda tired

Answer 55

ight

Answer 56

Buh i can still continue if u want

Answer 57

yes pls

Answer 58

if u dont bmind

Answer 59

Mk

Answer 60

where
a=2x a=2x and b=3 b=3
So (2x+3)(4x^2−6x+9) is the answer

Use this formula if ur confused how i got the answer- (a−b)(a^2+ab+b^2)

Since both terms are perfect cubes, factor using the difference of cubes formula,
a^3−b^3

Answer 61

but they arent perfect cubes though

Answer 62

im confuzzled

Answer 63

8. Explanation:
Step 1 :
To factor 81x^4 −1 we can use difference of squares formula:
I^2−II^2 =(I−II)(I+II)
After putting I=9x^2 and II=1 , we have:
81x^4−1=(9x^2−1)(9x^2+1)
Step 2 :
To factor 9x^2−1 we can use difference of squares formula:
After putting I=3x and II=1 , we have:
9x^2−1=(3x−1)(3x+1)

Answer 64

See if wht i wrote just now helps

Answer 65

i gtg now, thx tho for the help, i appreciate it very much
