Answer: C.  p(x) = -5x-x^2

This is the same as p(x) = -x^2-5x

The degree is the largest exponent to determine what kind of polynomial we're dealing with.

For choice C, the degree is 2, so we have a quadratic here.

Extra info:

  • Choice A is cubic because the largest exponent is 3 (degree = 3)
  • Choice B is a quartic of degree 4
  • Choice D is the same story as choice B
