question: find the remainder when the following function is divided by the linear factors indicated
#polynomial division thingy

Have you heard of the remainder theorem?
for a polynomial P(x) if P(x) is divided by (x-a) then the remainder is P(a)

not rlly
can u provide an example?

Substitute in x=-3 to your polynomial

Yes

is there any wrong w what I did here tho

is there any wrong w what I did here tho
what's up with the x value?
severe valve
the one i kinda crossed out?
marsh gale
i should've done 0x right?
yes
marsh gale
and then subtracted
marsh gale
try it again but put 0 as the coefficient of the missing ones hehe
severe valve
okay
marsh gale
if you message again i'll likely be in maths but i'll still check (maybe)

@marsh gale how would i do vii and viii?

using the remainder theorem i got 2a^3
lofty dome
how do u use it here
u do the usual method but instead let x = a
so x^3 + a^3 = a^3+a^3 = 2a^3
its my first time hearing of this method too its like 1000x quicker than long division 😭

so x^3 + a^3 = a^3+a^3 = 2a^3
ohhhh
ohhhhhhhh
thanks man
for viii would it be
let x = -a
x^3 - a^3 = -a^3 - a^3
-2a^3 ?
ah it's correct

NICEEE
