Write as a polynomial - \dfrac{ 2 }{ 7 } { a }^{ 2 } { y }^{ 7 } \left( 5a { y }^{ 2 } - \dfrac{ 1 }{ 2 } { a }^{ 2 } y- \dfrac{ 5 }{ 6 } { a }^{ 3 } \right)

Step-by-step explanation:

According to the statement, we have the algebraic equation and we must to rewrite it as a polynomial. Since there are two variables: , , we must observe the following definition of polynomial:

(1)

Where:

- Index.

- i-th Coefficient of the polynomial.

- Grade of the polynomial.

By means of algebraic handling, we have the following result:
