Answer 1

no

Answer 2

@Nnesha

Answer 3

@Michele_Laino

Answer 4

foil the left side and equate

Answer 5

my b didnt see u

Answer 6

soo how would tht go im still trying to get familiar with it

Answer 7

(x+6)(x-6)=x^2-36

Answer 8

you know that (a+b)(a-b)=a^2-b^2 yes ?

Answer 9

wait where u get 32 from

Answer 10

difference of squares do you remember that formula?

Answer 11

uhhhhhhhhhhh maybe:/

Answer 12

no may be yes or no

Answer 13

nope

Answer 14

ok let's go slow then
can you distribute (a+b)(a-b)

Answer 15

yes

Answer 16

ok go ahead

Answer 17

a^2-b^2

Answer 18

ok what about (x+6)(x-6)

Answer 19

x^2-16

Answer 20

where did 16 come from?

Answer 21

6+6 ohhh 6^2 soo x^2-6^2

Answer 22

does 6+6=6^2?

Answer 23

no brain fart my b

Answer 24

and 6+6=12 not 16?

Answer 25

what is 6x6

Answer 26

36

Answer 27

ok! do you know that 6^2 is the same as 6x6

Answer 28

yes

Answer 29

then why did you tell me 6+6=6^2?

Answer 30

didnt mean to i ment to say x^2-6^2

Answer 31

ok so x^-6^2=...

Answer 32

u mean \[x ^{2}-6^{2}\]

Answer 33

yes

Answer 34

so \[x^2-6^2=x^2-36\] yes?

Answer 35

(x+6)(x−6)

Answer 36

damn back at beginning

Answer 37

yes that's what we started with
\[(x+6)(x-6)=x^2-6^2=x^2-36\]

Answer 38

ok thats better now i know where 36 came from

Answer 39

so we have now \[x^2-36=x^2+cx+d \]

Answer 40

do you know what coefficients mean?

Answer 41

2 pairs right

Answer 42

no

Answer 43

why are doing this if you don't any idea of what a coefficient mean?
did you not study this ?

Answer 44

dang A number or symbol multiplied with a variable or an unknown quantity in an algebraic term.

Answer 45

ok yes that is a coef
now tell me the coefficients of this expression \[x^2+cx+d\]

Answer 46

x?

Answer 47

well x is the variable or unknown it can't be a coefficient

Answer 48

idk

Answer 49

the coefficient for this expression are 1, c and d

Answer 50

ok

Answer 51

read that definition of a coefficient and see if this is true
a coefficient is a number or symbol that is multiplied to unknown
1 is multilpied to x^2
c is multiplied to x
d is multiplied to x^0 (hidden unknown )

Answer 52

ok if you understand the concept what are the coefficients of this one x^2-36

Answer 53

yes its true

Answer 54

uhhhh x,2,36

Answer 55

incorrect

Answer 56

x is unknown 2 is a power not a coeff
36 is good but you missed - sign

Answer 57

hmmmk

Answer 58

go watch some tutorial videos about this you need to wok on this before you try this problem

Answer 59

ight

Answer 60

i could give you the answer but no point in that if you don't got why it is the correct one
first get the basics and then go to this level of problem
