Question

By using factor theorem determine whether q (x) is a factor of p (x) or not
p (x) = x3 - x2 - x - 2 , q (x) = x - 2

Answer 1

Answer:

yes

x=2

2^3-2^2-2-2

8-4-2-2

8-8=0

Answer 2

Answer:

put x=2 in p(x)

2^3 - 2^2 -2 -2 = 0 .

Hence remainder is 0.

Therefore q(x) is a factor of p(x)
