A polynomial is an expression which is a combination of constants and variables joined by mathematical operator. It contains different powers of same variables.
Zeroes of a polynomial is the value of variable which on put in the equation result in zero.
The number of zeros of a polynomial is the highest degree of the polynomial.
The highest degree of a cubic polynomial is three. So, there will be three zeros of cubic polynomial.
Final Answer:
There are three zeros of a cubic polynomial.
