Mathematics

Factored form of function: f(x)=(x+9)(x-9)(x+5) .

Zeros of function: x=-9,-5,9

Step-by-step explanation:

We have been given a function f(x)=(x^2-81)(x+5) . We are asked to find the factored form and zeros of our given function.

Using difference of squares a^2-b^2=(a+b)(a-b) , we can rewrite our given function as:

f(x)=(x^2-9^2)(x+5)

f(x)=(x+9)(x-9)(x+5)

Therefore, the factored form of our given function is f(x)=(x+9)(x-9)(x+5) .

To find the zeros of our given function, we will use zero product property. Upon equation our given function equals to zero we will get,

(x+9)(x-9)(x+5)=0

$(x+9)=0\text{ or }(x-9)=0\text{ or }(x+5)=0$

$x+9=0\text{ or }x-9=0\text{ or }x+5=0$

$x=-9\text{ or }x=9\text{ or }x=-5$

Therefore, the zeros of our given functions are x=-9,-5,9 .
