Question

verify is - 3 and 4 at the zeros of the polynomial 2 x cube minus 3 x square - 23 x + 12 then factorise the polynomial

Answer 1

p(x)=2x^3-3x^2-23x+12

g(x)=-3

evaluating p(x)=2x^3-3x^2-23x+12

                 p(-3)=2(-3)^3-3(-3)^2-23(-3)+12

                        =-54-27+69+12

                       =-91+91

                        =0

hence it is the zero of poly

hope it help you
