Answer:
The zeros of the given function
is
are -8 and -9.
Step-by-step explanation:
Given : Function 
We have to find the zeros of the functions.
Consider the given Function 
Since, we have to find the zeros of the given functions.
Put f(x) = 0
Thus, 
We can solve the given equation using middle term splitting method.
17x can be written as 8x + 9x
can be written as 
Taking x common from first two term and 9 common from last two terms, we have,

Simplify, we have,
or 
x = -8 and x = -9
Apply zero product rule,

Thus, The zero of the given function
is
are -8 and -9.
