The rational zeros of the function are
Explanation of Solution
Given information:
The functionis
Formula Used:
Rational Zero Test.
The formula is:
To find the zeros of the function, substitute the function
Calculation:
The function is
To find the zeros of function, use the Rational Zero Test.
The leading coefficient is 1 and the constant term is
Put
Thus,
To simplify the function, take
Rewrite the above polynomial as:
To solve the above quadratic equation, split the middle term.
To find the zeros of the function, substitute the function
Rewrite it as:
That is,
Or
Or
Hence, the rational zeros of the function are
