Question

Simplify the expression. 2(3y - 7) - 5y(2 - y)

Answer 1

2(3y - 7) - 5y(2 - y)

2*3y - 2*7 - 5y*2 -5y*(-y)

6y - 14 - 10y + 5y²

5y² + 6y - 10y - 14

5y² -4y - 14

Answer 2

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.`
