Answer
4$Y^{2}$ - 49
Work Step by Step
This problem requires us to multiple out a factored equation.
1. First multiply the 2Y terms, giving you 4$Y^{2}$
2. Then multiply 2Y and 7 , then 2Y and -7, giving us 14Y - 14Y
3. Then Multiply 7 and -7, giving us -49
4. Combine all these terms together to get 4$Y^{2}$ + 14Y - 14Y - 49
5. Simplify the equation to get 4$Y^{2}$ - 49
