Question

is the binomial x+2 a factor of x^3+x^2-16x-16?

Answer 1

a is a factor of p(x) iff (a-x) is a factor

in other words x+2 is a factor if -2 is a zero

Answer 2

if the division of both, that is \(\bf x^3+x^2-16x-16 \div x+2\) yields a "remainder" of 0, then yes

Answer 3

Is the remainder zero?
