Step-by-step explanation:
When you have a polynomial function, you can identify the grade of the function (the grade is the maximum potency) and this is the number of zeros that the function will have. In this case, you have a second-grade polynomial function that has 2 zeros.
Answer:
257
Step-by-step explanation:
The divisors of 72 which are composite number are
4,6,8,9,12,18,36,72 (composite numbers are those numbers which are formed by the multiplication of two whole numbers}
So the total number of divisors which are composite are = 8
So total number of subset 
In question it is said that also include empty set in count
So total number of subset =256+1=257
