Concept explainers
To find: all real zeros of the function.
The real zeros of the function
Given information:
The function
Formula used:
The Rational Zero Theorem:
If
Calculation:
Consider the function
Rational zero theorem:
Factors of constant term
Factors of leading coefficient
All possible combinations of
The function's zeros could be all or none of them.
Simplify and remove any duplicates.
Test the possible rational zero combinations by plugging into
division to see which ones generate a zero.
Only
Divide
which is negative, so the other
Therefore, the real zeros of the function
