For a polynomial p(x), the value of p(3) is -2. Which of the following must be true about p(x)?
a) x-5 is a factor of p(x)
b) x-2 is a factor of p(x)
c) x+2 is a factor of p(x)
d) The remainder when p(x) is divided by x-3 is -2.
The answer is d. However, I don’t understand why. Can someone help explain how you get to the answer? Thanks for your time.

SOLUTION: Which of the following is a factor of the… – Yeah, this is a tricky one. I actually think the way many students will get it is by elimination. Given p(3) = -2, we know nothing about x – 5, x – 2, or x + 2. So, choice D might not be intuitive, but at least it's related to p(3) somehow. Remember that if p(3) = 0, then we…kittendude kittendude. B) A root of f(x) is x = 5. iff(x)=(x−5)×something then f(5)=(5−5)×something i.e. f(5)=0 since f(5)=0 we say " a root of f(x) is 5" hope this helps, can i get brainliest please??
