Question

p(x) = x3 + 4x + 16 is divided by x + 2 , then find the remainder and hence determine whether x + 2 is a factor of p(x) or not​

Answer 1

Step-by-step explanation:

p(x)=x³+4x+16

g(x)=x+2

x+2=0

x=-2

p(-2)=(-2)³+4(-2)+16

= -8-8+16

= -16+16

= 0

therefore x+2 is the factor of p(x)

Answer 2

Answer:

Step-by-step explanation:

x^3 + 4x + 16 divided by x + 2

x^2 +
