Answer 1

The number of roots of a polynomial is always equal to the degree of the power, If the degree of polynomial is 1 then the root is 1

If degree is 10 then root is 10

`\text{ Degr}ee\text{ of Polynomial = Number of roots of polynomial}`

In the given, The order of polynomial is 5

SO, the roots is also five
