Question

If p(x)=x3+4x-5 is divided by
X+2 then find the remainder
and determine if (x+2) is a
factor of p(x) or not
option (a) 21 (b) 12 (c)-12 (d) -21​

Answer 1

Answer:

ans is (d)-21

Step-by-step explanation:

p(x)=3x+4x-5

x+2=0 => x=-2

now,

p(-2)=3(-2)+4(-2)-5

=-6-8-5

=-21

hence, (x+2) is not a factor of p(x)
