Concept explainers
(a)
To find : All the zeros of function
(a)
Answer to Problem 98CR
Explanation of Solution
Given information :
Concept used:
Zeros of polynomial: -
It is defined by as any real value of
Rational root theorem:
If the polynomial
Calculation:
Since, all coefficients are integers.
So, apply rational zeros theorem
The constant term is 51 and factor of 51 is
If
Check:
The quotient is
Since the remainder is
Now, find the roots of
So, the zeros of function
(b)
To find : linear factor of
