@Loser66

Answer 2

your attempt?

Answer 3

idk what the second part means

Answer 4

@Loser66

Answer 5

do you know long division? or synthetic?

Answer 6

long'

Answer 7

I have the anwer

Answer 8

show me your work

Answer 9

Its to much to type

Answer 10

the answer I got is x^2-2x-3 @Loser66

Answer 11

remainder 12

Answer 12

hey, how can I know whether it is your work or you just copy from the back of the book? show your work, please, use draw box

Answer 13

Answer 19

ok

Answer 20

can you see it?

Answer 21

no

Answer 22

dont submit a pdf

Answer 23

I can't open pdfs

Answer 24

One more try
x^2 -6x +13
|------------------
x+2 | x^3 - 4x^2 +x -6
-
x^3 +2x^2
----------------
0 -6x^2 +x
-
-6x^2 -12x
---------------------
0 -13x -6
-
-13x +26
-----------------
0 -32
so the remainder is -32

Answer 25

see it?

Answer 26

hey, I did all my best, give me your cupcake and I log out. hehehhe. joke.
Do you get it?

Answer 27

yeah

Answer 28

YEAH. means you got it, right?

Answer 29

but what is meant by the second part of the question?

Answer 30

it means the remainder factor is \(\dfrac{-32}{x+2}\)

Answer 31

huuuh?

Answer 32

I know it didn't show, -32 in the numerator, (x+2) in the denominator. Is it clear?

Answer 33

that is the remainder factor. got me? write it out on the paper

Answer 34

Help me with this one 3x^3−5x^2−16x+12 divided by (x+2). If (x+2) is a factor, determine the remaining factors.

Answer 35

hey, hey, it's exactly what we 've just done. DO IT. show me you got something from my guiding. I can check. I don't want to be your free answer service. you do it by yourself now. Show me your brain, please

Answer 36

k wait

Answer 37

I got .. 3x^2 -11x +6 Reminder 0

Answer 38

@Loser66

Answer 39

?????

Answer 40

nope, redo. If you want me trust you, show the whole work like what I did. I could do it, why couldn't you? Moreover, it's your problem, right? One more try, please

Answer 45

but the second part of the question???

Answer 46

it's me, I am a rude person. don't you know it? hehehe ,
the second part is "no remainder fraction"

Answer 47

Complete the square to find the vertex of each quadratic function. State the vertex.
y=2x^2+8x−2

Answer 48

your idea?

Answer 49

x1=−2−5√
x2=−2+5√

Answer 50

oops
square root 5

Answer 51

nope, not that way

Answer 52

idk

Answer 53

help me

Answer 54

I am thinking the easiest way to show you

Answer 55

question : 2x^2 or (2x)^2

Answer 56

y=2x^2+8x−2

Answer 57

we got trouble then. hehehe. let see what I can do for you

Answer 58

ok, factor 2 out, you have y = 2 ( x^2+4x -1)

Answer 59

follow me carefully and stop me when you don't get me. Ok? i will post step by step

Answer 60

ok

Answer 61

I just pick the ( ) part to solve first:
x^2 + 4x + 4 -4 -1 = (x +2)^2 -5
got me ??

Answer 62

no?

Answer 63

kind of

Answer 64

question?

Answer 65

are you doing perfect squares?

Answer 66

yup

Answer 67

completeing *

Answer 68

ok

Answer 69

got it? right?

Answer 70

ya

Answer 71

not finish yet, just first step

Answer 72

ok

Answer 73

now, put it back to y
y = 2 ( ) , right? and from the previous post , I have ( ) = (x+2) ^2 -5
so y = 2 ((x+2)^2 -5) = 2 (x+2)^2 -10
got it?

Answer 74

ya

Answer 75

the vertex?

Answer 76

so, we have the form of vertex form y = a (x -h)^2 + k where h,k is vertex of parabola
your is y = 2 (x +2) ^2 -10 , can you tell me h =?? k =??

Answer 77

-2,10

Answer 78

-2, -10, not 10

Answer 79

Yes or No?

Answer 80

yes

Answer 81

vertex is -2,-10

Answer 82

righttt????

Answer 83

YES
hehehe.... this rude guy is acceptable, right? hehehe

Answer 84

lol

Answer 85

y=-x^2+5x−3

Answer 86

another one

Answer 87

I don't know how to solve it, friend, hehehe... need rest.

Answer 88

one more!!!

Answer 89

post in new one, I will tag Mertsj
