Does the equation below demonstrate closure of polynomials under multiplication and how? (2x^2+4)(x^3+2x+1)=2x^5+8x^3+2x^2+8 x+4

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
