Answer 1

@HawkCrimson

Answer 2

well what can be factored out of all the terms?

Answer 3

let her do it by herself :) ive been helping her and i want to see how far she'll get :D

Answer 4

ahh okay @HawkCrimson yes lets see lol

Answer 5

if u r not too comfortable with actually factoring it, you could always do the equations from the answer choices, and see which one matches the pre-factored form... first FOIL then multiply it all by 2.

but yes, you should try it first yourself! :)

Answer 6

thx @johnweldon1993 , so @Gabylovesyou do u know how to start this?

Answer 7

but factoring it normally is more efficient :)

Answer 8

Answer 9

yup! I totally agree :)

Answer 10

sorry i was out... ok ummm hold up

Answer 11

lol i havnt left so ok xD

Answer 12

how do i do it when its an exponent?

Answer 13

u remember the 4 steps i taught u?

Answer 14

cmon plz tell me u wrote it down some where??

Answer 15

-,- idk how to do this one..

Answer 16

but do u have the 4 steps i showed u?

Answer 17

The GCF etc.. right?

Answer 18

the one which starts off
1st Step:
(x ) (x )

Answer 19

remember that?

Answer 20

ill show u again if u dont remember

Answer 21

?

Answer 22

;/

Answer 23

lol it's ok :)

Answer 24

\[2x ^{2} − 6x − 56\]
(2x - 14)(x + 4)

Answer 25

u there? i need u to be here for me too explain it

Answer 26

sorry im here..

Answer 27

ok u have time on ur hands?

Answer 28

yes

Answer 29

cool :D

Answer 30

Step 1:
(x +)(x +)

Answer 31

actually gaby, this isnt something u learn from steps, u have to practice till u get the feel of it so im just going to explain it then u'll tell me if u understand and we'll practice with more questions and if ur like me then u'll forget it by tomorrow and we'll go at it again :P

Answer 32

math's just a bi.tch like that xD

Answer 33

i thought u had time on ur hands?

Answer 34

lol^

Answer 35

i am like u .... LMAO ... i do but my OS is acting stupid

Answer 36

wat is OS?

Answer 37

openstudy

Answer 38

lol that's ok, everyone's openstudy was acting dump yesturday

Answer 39

lol ok..

Answer 40

\[ 2x ^{2} − 6x − 56\] ok so back too ur question :P

Answer 41

lol .... so first ?

Answer 42

(x + ) (x + )

Answer 43

next we list all the factors of 56
1 2 4 7
56 23 14 8

Answer 44

(2x + ) (x + )

Answer 45

one of these combinations will be placed in the empty spaces in (2x + ) (x + )

Answer 46

ok...

Answer 47

so lets choose 4 and 14
(2x + 4) (x + 14)

Answer 48

from here u should be able too see (2x - 14) (x + 4)

Answer 49

is ur answer

Answer 50

u there?

Answer 51

UGH OS IS KILLING ME HERE.. lol

Answer 52

ohh ok ...

Answer 53

let me give u an easier question and we'll work up from there ok?

Answer 54

ok :)

Answer 55

\[x ^{2}+3x+2\]

Answer 56

factorize that

Answer 57

i need to list all the factors of 2 ?

Answer 58

yep

Answer 59

1 2 -1 -2

Answer 60

i choose 2 and -2... am i going good?

Answer 61

2 and -2 isnt a factor of 2. only 1 and 2 r factors of 2

Answer 62

-.- ok then i pick 1 and 2 lol

Answer 63

yay :D

Answer 64

wat is ur final answer?

Answer 65

(x + 1)(x + 2) ?

Answer 66

yes! congrates :D

Answer 67

OMG YAYAYYAYAYAYAYYA ...

Answer 68

:D next question now :)

Answer 69

\[x ^{2}+5x+6\]

Answer 70

Factorize that :))

Answer 71

1 2 3 6
i pick
2 and 6
(x + 2)(x + 6) ????

Answer 72

no cause 2*6 = 12

Answer 73

so 2 and 3

Answer 74

(x + 2)(x + 3)

Answer 75

yes :D wats ur final answer?

Answer 76

yes :)) next question! this is math u do a bunch of questions :P

Answer 77

Factor completely: x^2 − 2x + 5

(x + 5)(x − 1)

Prime

(x − 5)(x − 1)

(x + 5)(x + 1) <---------- ANSWER

Answer 78

no cause (x + 5)(x +1) = x^2 +6x +5

Answer 79

hmmmm so then C ?

Answer 80

x^2 -2x +5 is that a question?

Answer 81

C for wat? lol now im lost xD

Answer 82

LOL .......is this prime?

Answer 83

forget the original question, we need practice witth easier ones :P

Answer 84

u have time on ur hands correct?

Answer 85

YES .. LOL

Answer 86

so next question?

Answer 87

yes

Answer 88

\[x ^{2}-x-12\]

Answer 89

u there?

Answer 90

factor 12...
1 2 3 4 6 12

Answer 91

2 and 6..

Answer 92

(x + 2)(x + 6)

Answer 93

to check ur answer expand wat u have in the brackets

Answer 94

x * x = x
x * 6 = 6
2 * x = 2
2 * 6 = 12

im wrong lol

Answer 95

the point is u know how to check ur answers now :D just try a different option :)

Answer 96

answer is (x - 4) (x + 3)

Answer 97

YES! :D ur getting the hang of it :)
