FOIL!! First outside inside last? am i on the right track?
biocross
says

no
biocross
says
16 years ago
like polynomial factorization !
biocross
says

x3 - x2 + x -6 = (x2 -3) (x-2) (x+3)
biocross
says
16 years ago
something that looks like that
biocross
says

but what i pasted is wrong. if its right im a genius

hasn't done any math more complicated than multiplication and division since high school
carissa
says

factorize (x-2)(x+2)= don't you use FOIL for that?
carissa
says
16 years ago
or do i have it backwards? lol.
biocross
says

i am confused!

that example you put above is not factorable.. fully
carissa
says
16 years ago
x^3-x^2+x-6
carissa
says
16 years ago
x^3-x^2+x=6
carissa
says

x(x^2-x+1)=6

you can factor polynomials like that into 3 factors as he showed there.. through some kind of math voodoo.
carissa

but that innner equation can't be further reduced into two polynomials. at least i can't figure a way
zenriot
says
16 years ago
the way you've done it, no. But there's a way to factor that first equation into 3 (x + n) terms.

he tried to show me last night - it's voodoo!
carissa

well i went to catholic highschool and jr high. they don't teach us voodoo there.. HAH
