Question

how do you do this sum??? "use the factor theorem to determine whether g(x)is a factor of p(x):

Answer 1

(i) p(x) = \[2x ^{3} + x ^{2}-2x-1,if g(x)=x+1

Answer 2

you have a choice. you can replace x by -1 in p(x). if you get 0 then x+1 is a factor.

Answer 3

in ohter words if p(-1)=0 then p(x)=(x+1)Q(x)

Answer 4

thanks!

Answer 5

when it says " use the factor theorem, that is what it wants you to do

Answer 6

or you could just divide but that doesn't use the theorem

Answer 7

or you could just divide but that doesn't use the theorem

Answer 8

no the theorems what i need
