\[\huge Use \ (x+a) (x+b)=x^2+ax+bx+ab \\ \huge = x^2 + 4x + 3x + 12 \]

@rannsan do u get that
AriPotta
  • AriPotta
that's FOIL, right? i think it would be better if you explained what exactly to do rather than giving an equation, but that's just me
anonymous
  • anonymous
I did not get that
AriPotta
  • AriPotta
you have to use FOIL. First times First, Outer times Outer, Inner times Inner, and Last times Last

1 multiply the first numbers in both the parenthesis x & x 2 multiply the outer numbers in both parenthesis ( x & b) 3 multiply the inner numbers (x&a) 4 multiply the last numbers ( a &b) Source(s): wiki

ok this is gonna sound really stupid on my part but how can I multiply if I don't know what x is?
AriPotta
  • AriPotta
|dw:1348910674893:dw| x times x equals 2x
AriPotta
  • AriPotta
but that shows what's what if you can understand it
hartnn
  • hartnn
* x times x = x^2
AriPotta
  • AriPotta
wait no, x^2
AriPotta
  • AriPotta
yea, sorry!
anonymous
  • anonymous
ok
AriPotta
  • AriPotta
does that make sense? do you know what to do now?
anonymous
  • anonymous
x^+12?
anonymous
  • anonymous
x^2+12 that is
AriPotta
  • AriPotta
what did you do to get that? you're missing something
anonymous
  • anonymous
x^2+7x+12
AriPotta
  • AriPotta
yep :)

whewwwwwwwwwwwwww

good job :D
UsukiDoll
  • UsukiDoll
lol what's with that big equation? XD
AriPotta
  • AriPotta
a confusing equation of FOIL lol
UsukiDoll
  • UsukiDoll
I know right. BIG FONT!
hartnn
  • hartnn
isn't LATEX interesting?
UsukiDoll
  • UsukiDoll
that program that allows words and equations to go together

what's latex? A milky fluid found in many plants, such as poppies and spurges, that exudes when the plant is cut and coagulates on exposure to the air. The latex of the rubber tree is the chief source of natural rubber?
hartnn
  • hartnn
lol!
hartnn
  • hartnn
can u write this : \(x^2\)
AriPotta
  • AriPotta
\[x ^{2}\]
UsukiDoll
  • UsukiDoll
\[x^{2}\]
AriPotta
  • AriPotta
so the program that allows us to write that is LATEX? what does it mean?
AriPotta
  • AriPotta
like, what's it stand for?
UsukiDoll
  • UsukiDoll
yeah for higher level math courses to write papers about equations. lol is it hard to write a paper about a formula? I may need to do that next semester.
hartnn
  • hartnn
yup, the formatting way is called latex...
UsukiDoll
  • UsukiDoll
ummm Lamb Alligator Tiger Elephant Xanda lol Xanda Panda
hartnn
  • hartnn
lol !
UsukiDoll
  • UsukiDoll
does anyone have experience in Linear Algebra?
AriPotta
  • AriPotta
when i first read your comment "isn't LATEX interesting?" i thought you were making a sexual joke and latex was in all caps because you were emphasizing what you wanted.
UsukiDoll
  • UsukiDoll
oh like Latex ahhem all the boys should know
UsukiDoll
  • UsukiDoll
LOL Martha Speaks icon
hartnn
  • hartnn
any specific question @UsukiDoll
UsukiDoll
  • UsukiDoll
yeah you got experience in LInear Algebra? what's it like?
AriPotta
  • AriPotta
a harry potter, martha speaks icon
AriPotta
  • AriPotta
martha's decked out in scar and wand
hartnn
  • hartnn
much like algebra.....equations and matrices.....
UsukiDoll
  • UsukiDoll
so you've taken the course?
hartnn
  • hartnn
i have completed that years ago.....
AriPotta
  • AriPotta
years upon years.
UsukiDoll
  • UsukiDoll
lol help a future mathematician out X)
hartnn
  • hartnn
sure....whats the doubt ?
UsukiDoll
  • UsukiDoll
ummm everything. lol I'm scared of taking Linear Algebra. x*
hartnn
  • hartnn
don't be scared, with practice its easy.....and i'll be here to help u with any difficult problem....
