Question

@jacob194485 ok one more
Factor completely −5x^3 + 10x^2.

A. Prime
B. −x(5x2 − 10x)
C. 5x(−x2 + 2x)
D. −5x2(x − 2)
but this time dont give me the answer i need to learn how to do it!_! plz!

Answer 1

i am tagging every one on my fans list lol

Answer 2

@jordan123321 @Micah1mcdugle @roz_mar23 @MinightTheWolfie @alanwallace

Answer 3

that r online

Answer 4

what do they have in common?

Answer 5

factor that out

Answer 6

the only thing i see is the x

Answer 7

(-5) is common to both coefficients
x^2 is common to both variables
(- 5x^2) (x - 2)

Answer 8

r u on the question or the answer choices

Answer 9

the questions. that hasjust been explained

Answer 10

now, to factor out, you must look at the two or more independent variables

Answer 11

you must check for the co-efficient and also the powers

Answer 12

THE X'S ?

Answer 13

yes, x is the independent variable separated by + sign. now note before u can factor out, there must be a separation with either + or -

Answer 14

R THE INDEPENDENT VARIABLES THE X'S?

Answer 15

ohh ohkay

Answer 16

the variable involved is just X

Answer 17

now, lets look at some examples before working on that,.....
facor out ..
\[x ^{4}+x\]

Answer 18

can you try factorize that?

Answer 19

ok i will try

Answer 20

x(x^4)??

Answer 21

hmmmm.wrong

Answer 22

now have you heard of distribution property?

Answer 23

distribution property states that a(b+c)=ab +ac

Answer 24

its just a way of opening the bracket

Answer 25

ummm ive hered tha but i thought it was a+b=c^2

Answer 26

nooooooo

Answer 27

it says that 2(1+3) is same as 2(1)+2(3)

Answer 28

i am sooo soorry for being so dumb and frustrating

Answer 29

lol

Answer 30

try that and tell me if u get thesame thing

Answer 31

yes is that the foil presedure

Answer 32

just a start to it

Answer 33

now, look at \[x ^{4} +x\]

Answer 34

ok i am looking lol

Answer 35

first, they are asking if there is a common thing between x^4 and x

Answer 36

the x
??

Answer 37

now recal that the things to watch out are 1) the variables and power,
@
2) the co-efficient of the two separated variables

Answer 38

now, what is the co-efficient of x^4?

Answer 39

you there?

Answer 40

do you have idea?

Answer 41

sorry had to do something

Answer 42

can you answer the question ?

Answer 43

what is the co-efficient of x^4?

Answer 44

i am not sure

Answer 45

i am so confused i will give you medal any way

Answer 46

please stay let me teach you and i promise you will understand. never give up

Answer 47

@i<3u43v4

Answer 48

i am triing but it is hard i hat f*cking school
ok go on

Answer 49

the co-efficient of a variable is the number beside or multiplying that veriable

Answer 50

5x. the co-effiecient of that 5x or x is the 5

Answer 51

so it is 4

Answer 52

here the co-effiecient of \[x ^{4}\]

Answer 53

is 1

Answer 54

there is no number 1 tho

Answer 55

note this, every variable or number is multiplied by invisible 1 and devided by invisible 1

Answer 56

e.g \[1x/1\]

Answer 57

ok so it is always 1 right?

Answer 58

but in maths is better to say x instead of 1x/1

Answer 59

i have a question for you. \[2\times1=\]

Answer 60

ok

Answer 61

2

Answer 62

any thing times 1 is it self

Answer 63

now what that means is that 2 is times d by 1 and at the same time divided by 1, this is how it ought to be \[(2\times1)\div1\]

Answer 64

but in maths we will just take 2 rather than\[ (2\times 1)\div1\]

Answer 65

now did you understand that step?

Answer 66

did you understand why we always say 2 instead of (2X1)/1?

Answer 67

waw. later den

Answer 68

yes i under stand now!!

Answer 69

it is d?

Answer 70

@GIL.ojei

Answer 71

yap

Answer 72

THX

Answer 73

thanks to openstudy.

Answer 74

Sorry i never got the notification if you still need the answer its −5x2(x − 2)
