Use synthetic division to find P(3) for P(x)=x^46x^34x^26x2
Can someone please explain

hard to explain synthetic division here. If you know how to do it, then you just need to know that
p(3) is the remainder after doing the division.
That's because p(x) = (x3)*q(x) + p(3)
If x3 divides p(x), then there is no remainder: p(3) = 0.
