PIE GUY MATH QUESTIONS

Answer 1

write the expression in factored form 5x^2+5 my answer is 5(x^2+1)

Answer 2

the only thing the two terms have in common is the 5, so you are correct

Answer 3

i got more questions

Answer 4

go for it

Answer 5

awesome :D

Answer 6

factor b^2+4b+3

Answer 7

my answer is (b+4) (b+3)

Answer 8

Correct!

Answer 9

hi andrew did you read the article

Answer 10

Wait no

Answer 11

For the answer part

Answer 12

it will explain evryhting you need to know about this site

Answer 13

I know, I'll get to it

Answer 14

But for your answer, think of factors that multiply to 3 and add to 4

Answer 15

my next question is factor x^2-12x+11

Answer 16

wait im wrong?

Answer 17

Yeah you're wrong

Answer 18

Sorry, read it wrong

Answer 19

(b+3) (b+1)

Answer 20

Correct for real this time

Answer 21

ok the second question answer is (x-1) (x+11)

Answer 22

Very close

Answer 23

i got it

Answer 24

No, it's not, it should be (x - 1)(x - 11)

Answer 25

(x-11) (x-1)

Answer 26

beat me first

Answer 27

In what?

Answer 28

answering the question

Answer 29

well you did get 2 place

Answer 30

Show you how?

Answer 31

WHAT IS GOING ON!?

Answer 32

noting?

Answer 33

?

Answer 34

the next question is b^2-2b-8

Answer 35

What's your answer?

Answer 36

(b-2) (b+4)

Answer 37

So close again!

Answer 38

-_-

Answer 39

Your answer whould result in the trinomial b^2 + 2b - 8.

Answer 40

(b - 4)(b +2). That's the answer to this.

Answer 41

AWWWWWWWWW

Answer 42

Yeah

Answer 43

How do you calculate your answers?

Answer 44

i do it in my mind

Answer 45

Uh...I do it in my mind because I've done it like a million times, but since you're just starting, shouldn't you do it on paper until you get the hang of it?

Answer 46

I see your point ..... I guess your right maybe I should slow down

Answer 47

my next question is 2x^2+5x+2

Answer 48

If you feel confident enough that you think you can do it, just start off by writing down important stuff so that you don't overload your mind. Basically write down loose numbers.

Answer 49

And to the problem, we finally get to the grouping! Not even I do this in my head.

Answer 50

I see thanks might used them in my upcoming test on Tuesday

Answer 51

i don't know how to do this I only this part 2(x^2+?+1)

Answer 52

Why are you taking out the 2?

Answer 53

There's no GCF

Answer 54

ohhh

Answer 55

Do you get it now?

Answer 56

not really wanna skype

Answer 57

me and my tutor do this

Answer 58

he explains to me manually

Answer 59

in talking

Answer 60

So basically, because 2x^2+5x+2 has a leading x^2 with a coefficient, you multiply the squared variable with the constant and find 2 factors that multiply to this product and add up to 5 since it's the middle term.

Answer 61

So find factors that multiply to 4 and add upp to 5.

Answer 62

4 and 1

Answer 63

Do you understand so far?

Answer 64

yes ;D

Answer 65

Now reinsert these factors in the place of 5x like so: 2x^2 + 4x + x + 2. (Note, the order that they're inserted doesn't matter as long as they are in the middle.

Answer 66

With me at this point?

Answer 67

yes

Answer 68

Ok, now group the first two terms and the second 2 terms. (2x^2 + 4x) + (x + 2). Now factor out the GCF of both of these binomials separately. The result should be 2x(x + 2) + (x + 2).

Answer 69

so we get (4x+2x)+ (2x)

Answer 70

No matter what happens, the two binomials inside the parenthases should be the same. If they aren't look for an error. (A common mistake is leaving a negative inside, so all you would have to do is also factor out the negative as well.) And we still aren't done, so your answer is incorrect.

Answer 71

Do you get it?

Answer 72

-_- kind of?

Answer 73

What part is confusing you?

Answer 74

keep going...

Answer 75

Ok, now group the first two terms and the second 2 terms. (2x^2 + 4x) + (x + 2). Now factor out the GCF of both of these binomials separately. The result should be 2x(x + 2) + (x + 2).

Answer 76

Yeah, but what part of it?

Answer 77

that is the part

Answer 78

Do you get grouping the first and last 2 terms together?

Answer 79

ummm no?

Answer 80

Alright, you have a 4 term polynomial when you insert the factors in again right?

Answer 81

i know to get 5 we got 4x and 1x

Answer 82

Alright, because 4x + 1x = 5x, it can replace 5x right? That's what we did there.

Answer 83

yes

Answer 84

So at that point, you should have 2x^2 + 4x + x + 2 right?

Answer 85

yes

Answer 86

Now, what you're supposed to do here is put parentheses around the first two terms: (2x^2 + 4x) and the last two terms: (x + 2) separated by an addition sign.

Answer 87

k but why do we put them in parentheses

Answer 88

This is why this process is called "grouping" it's just a part of the process.

Answer 89

ok..

Answer 90

Do you get it?

Answer 91

yes then we foil?

Answer 92

No.

Answer 93

ok..?

Answer 94

what's the next step..?

Answer 95

What we have at this point is (2x^2 + 4x) + (x + 2) right?

Answer 96

yes

Answer 97

Now, find the GCF of both binomials SEPARATELY.

Answer 98

For the first binomial, you can factor out 2x because there it is common right?
