i do not get this
use division to determine whethe the binomial is a factor of f(x)
F(x)=x^3+20x32; x2
yes or no

Algebra 
Reiny,
3 is a factor of 12 because 3 divides exactly into 12 leaving no remainder
similarly if x2 is a factor of x^3+20x32 then it must divided exactly into it leaving no remainder.
so...
divide x^3+20x32 by x2 and see what happens.
