The given expression : $2(3y - 7) - 5y(2 - y)$

Multiply 2 and 5y inside the terms in the brackets corresponding to them respectively , we get

$6y-14-10y+5y^2$

Combine the like terms and arrange in order  , we get

$5y^2+6y-10y-14\\\\=5y^2-4y-14$

Hence, the simplified form of the given expression : $5y^2-4y-14$
