Question

verify whether the indicated numbers are zeros of their corresponding polynomials.
(a). Q(s)=-4s^3+7s^2-24;s=-4and1​

Answer 1

Answer:

-4s³+7s²-24

when s=-4

-4(-4)³+7(-4)²-24

-4(-64)+7(16)-24

256+112-24

368-24=344

-4 is not the zero of given polynomial.

when s=1

-4(1)³+7(1)²-24

-4+7-24

-28+7=-21

1 is not the zero of given polynomial
