Answer 3

Solving (2y + 1/4)²

To solve the expression (2y + 1/4)², we can use the formula for squaring a binomial, which is (a + b)² = a² + 2ab + b². In this case, a = 2y and b = 1/4.

Using the formula, we can expand and simplify the expression as follows:

(2y + 1/4)² = (2y)² + 2 * (2y) * (1/4) + (1/4)²

Now, let's simplify each term step by step.

(2y)² = 4y²

2 * (2y) * (1/4) = 2y * 1/2 = y

(1/4)² = 1/16

Putting it all together:

(2y + 1/4)² = 4y² + y + 1/16

So, the simplified form of (2y + 1/4)² is 4y² + y + 1/16.
