## Step-by-step Solution

Problem to solve:

$\left(2+\sqrt{y}\right)\left(2-\sqrt{y}\right)$

Specify the solving method

1

Multiply the single term $2-\sqrt{y}$ by each term of the polynomial $\left(2+\sqrt{y}\right)$

$2\left(2-\sqrt{y}\right)+\sqrt{y}\left(2-\sqrt{y}\right)$
2

Multiply the single term $2$ by each term of the polynomial $\left(2-\sqrt{y}\right)$

$4-2\sqrt{y}+\sqrt{y}\left(2-\sqrt{y}\right)$

$2\left(2-\sqrt{y}\right)+\sqrt{y}\left(2-\sqrt{y}\right)$

Learn how to solve special products problems step by step online. Solve the product (2+y^1/2)(2-y^1/2). Multiply the single term 2-\sqrt{y} by each term of the polynomial \left(2+\sqrt{y}\right). Multiply the single term 2 by each term of the polynomial \left(2-\sqrt{y}\right). Multiply the single term \sqrt{y} by each term of the polynomial \left(2-\sqrt{y}\right). When multiplying exponents with same base we can add the exponents.
