my b didnt see u
anonymous
  • anonymous
soo how would tht go im still trying to get familiar with it
xapproachesinfinity
  • xapproachesinfinity
(x+6)(x-6)=x^2-36
xapproachesinfinity
  • xapproachesinfinity
you know that (a+b)(a-b)=a^2-b^2 yes ?
anonymous
  • anonymous
wait where u get 32 from
xapproachesinfinity
  • xapproachesinfinity
difference of squares do you remember that formula?
anonymous
  • anonymous
uhhhhhhhhhhh maybe:/
xapproachesinfinity
  • xapproachesinfinity
no may be yes or no
anonymous
  • anonymous
nope
xapproachesinfinity
  • xapproachesinfinity
ok let's go slow then can you distribute (a+b)(a-b)
anonymous
  • anonymous
yes
xapproachesinfinity
  • xapproachesinfinity
ok go ahead
anonymous
  • anonymous
a^2-b^2
xapproachesinfinity
  • xapproachesinfinity
ok what about (x+6)(x-6)
anonymous
  • anonymous
x^2-16
xapproachesinfinity
  • xapproachesinfinity
where did 16 come from?
anonymous
  • anonymous
6+6 ohhh 6^2 soo x^2-6^2
xapproachesinfinity
  • xapproachesinfinity
does 6+6=6^2?
anonymous
  • anonymous
no brain fart my b
xapproachesinfinity
  • xapproachesinfinity
and 6+6=12 not 16?
xapproachesinfinity
  • xapproachesinfinity
what is 6x6
anonymous
  • anonymous
36
xapproachesinfinity
  • xapproachesinfinity
ok! do you know that 6^2 is the same as 6x6
anonymous
  • anonymous
yes
xapproachesinfinity
  • xapproachesinfinity
then why did you tell me 6+6=6^2?
anonymous
  • anonymous
didnt mean to i ment to say x^2-6^2
xapproachesinfinity
  • xapproachesinfinity
ok so x^-6^2=...
anonymous
  • anonymous
u mean \[x ^{2}-6^{2}\]
xapproachesinfinity
  • xapproachesinfinity
yes
xapproachesinfinity
  • xapproachesinfinity
so \[x^2-6^2=x^2-36\] yes?
anonymous
  • anonymous
(x+6)(x−6)
anonymous
  • anonymous
damn back at beginning
xapproachesinfinity
  • xapproachesinfinity
yes that's what we started with \[(x+6)(x-6)=x^2-6^2=x^2-36\]
anonymous
  • anonymous
ok thats better now i know where 36 came from
xapproachesinfinity
  • xapproachesinfinity
so we have now \[x^2-36=x^2+cx+d \]
xapproachesinfinity
  • xapproachesinfinity
do you know what coefficients mean?
anonymous
  • anonymous
2 pairs right
xapproachesinfinity
  • xapproachesinfinity
no
xapproachesinfinity
  • xapproachesinfinity
why are doing this if you don't any idea of what a coefficient mean? did you not study this ?
anonymous
  • anonymous
dang A number or symbol multiplied with a variable or an unknown quantity in an algebraic term.
xapproachesinfinity
  • xapproachesinfinity
ok yes that is a coef now tell me the coefficients of this expression \[x^2+cx+d\]
anonymous
  • anonymous
x?
xapproachesinfinity
  • xapproachesinfinity
well x is the variable or unknown it can't be a coefficient
anonymous
  • anonymous
idk
xapproachesinfinity
  • xapproachesinfinity
the coefficient for this expression are 1, c and d
anonymous
  • anonymous
ok
xapproachesinfinity
  • xapproachesinfinity
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 )
xapproachesinfinity
  • xapproachesinfinity
ok if you understand the concept what are the coefficients of this one x^2-36
anonymous
  • anonymous
yes its true
anonymous
  • anonymous
uhhhh x,2,36
xapproachesinfinity
  • xapproachesinfinity
incorrect
xapproachesinfinity
  • xapproachesinfinity
x is unknown 2 is a power not a coeff 36 is good but you missed - sign
anonymous
  • anonymous
hmmmk
xapproachesinfinity
  • xapproachesinfinity
go watch some tutorial videos about this you need to wok on this before you try this problem
anonymous
  • anonymous
ight
xapproachesinfinity
  • xapproachesinfinity
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
