Question

verify whether the indicated numbers are zeroes of their corresponding polynomials.
q(s)=-4s^3+7s^2-24, s=-4 and 1

Answer 1

Answer:

Here you go!

Step-by-step explanation:

1. When s= -4

        q(-4)= -4(-4)³+7(-4)²-24

                = (-4x-64)+(7x16)-24

                = 256+112-24

                = 344

                          So -4 is not a zero of this polynomial.

     2. When s= 1

          q(1)= -4(1)³+7(1)²-24

                = -4+7-24

                = -21

                        So 1 is also not a zero of the given polynomial.

             Therefore the given value of s= -4,1 are not the zeroes of this polynomial. Ans
