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:

p(x)=x3+4x-5

x = -2

p(-2)= -6+(-8)-5=0

by solving this equation remainder will be 19

and

no (x+2) is not the factor of p(x)
