Concept explainers
To find: all real zeros of the function.
The real zeros are just
Given information:
The function
Formula used:
The Rational Zero Theorem:
If
Calculation:
Consider the function
Then
Factors of constant term
Factors of leading coefficient
All possible combinations of
Some or none may be zeros of the function.
Simplify and eliminate duplicates.
Test the possible rational zeros.
Divide
The quotient is
Remainder is
The factors are now
Checking the discriminant for the quadratic factor
it's negative, so the other two zeros are imaginary.
The real zeros are just
