14y+2y(6-y)

To simplify the expression \( 14y + 2y(6 - y) \), follow these steps:

1. Distribute the \( 2y \) in the second term: \[ 2y(6 - y) = 2y \cdot 6 - 2y \cdot y = 12y - 2y^2 \]

2. Now substitute this back into the original expression: \[ 14y + (12y - 2y^2) \]

3. Combine like terms: \[ 14y + 12y = 26y \]

4. The expression now becomes: \[ 26y - 2y^2 \]

So, the simplified form of the expression \( 14y + 2y(6 - y) \) is: \[ -2y^2 + 26y \]
