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
