Question

Consider the polynomial function (x+3)(x+9)(x-6)=0. Wich of the following are zeros of the function?Select all that apply

-9
-6
-3
0
3
6
9

Answer 1

Given: The polynomial function (X+3)(X+9)(X-6) = 0

We shall test above function with the given values of zeros as - 9, - 6, - 3, 0, +9, + 6, +3

For the given polynomial function (X+3)(X+9)(X-6) = 0, their zeros can be calculated as

either, (X+3)= 0, for this X = - 3

or, (X+9) = 0, for this X = - 9

or, (X-6) = 0, for this X = +6

Hence, the zeros of the given polynomial will be -3, +6 and -9 only
