Definition of Degree: The degree of a polynomial is the highest power of the variable x that appears in the polynomial with a non-zero coefficient.
Combine Like Terms: First, we combine like terms in the polynomial f(x)=2x3+7x3−4x−12. The like terms here are the terms with x3.
Simplify Polynomial: Combining the like terms gives us f(x)=(2x3+7x3)−4x−12, which simplifies to f(x)=9x3−4x−12.
Identify Highest Power: Now that we have simplified the polynomial, we can see that the highest power of x is 3 in the term 9x3.
Degree of Polynomial: Therefore, the degree of the polynomial f(x)=9x3−4x−12 is 3.
