Answer 2

Simplifying the Expression (2a+b)2-(2a-b)2

To simplify the given expression (2a+b)2-(2a-b)2, we can expand the squares and then combine like terms.

Expanding (2a+b)2: (2a+b)2 = (2a+b)(2a+b) = 4a^2 + 4ab + b^2

Expanding (2a-b)2: (2a-b)2 = (2a-b)(2a-b) = 4a^2 - 4ab + b^2

Now, we can substitute these expansions back into the original expression and simplify.

Substituting the expansions: (2a+b)2-(2a-b)2 = (4a^2 + 4ab + b^2) - (4a^2 - 4ab + b^2)

Simplifying the expression: = 4a^2 + 4ab + b^2 - 4a^2 + 4ab - b^2 = 8ab

The simplified expression is 8ab.

This is the result of simplifying the given expression (2a+b)2-(2a-b)2.
