Answer: The required simplified form of the given expression is [tex]5y^2-4y-14.[/tex]
Step-by-step explanation: We are given to simplify the following expression :
[tex]E=2(3y-7)-5y(2-y).[/tex]
To simplify the given expression, we need to evaluate the bracket first.
The simplification is as follows :
[tex]E\\\\=2(3y-7)-5y(2-y)\\\\=6y-14-10y+5y^2\\\\=5y^2-4y-14.[/tex]
Thus, the required simplified form of the given expression is [tex]5y^2-4y-14.[/tex]
