Answer:  The required simplified form of the given expression is 5y^2-4y-14.

Step-by-step explanation:  We are given to simplify the following expression :

E=2(3y-7)-5y(2-y).

To simplify the given expression, we need to evaluate the bracket first.

The simplification is as follows :

E\\\\=2(3y-7)-5y(2-y)\\\\=6y-14-10y+5y^2\\\\=5y^2-4y-14.

Thus, the required simplified form of the given expression is 5y^2-4y-14.
