Solved example of algebra

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

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

$2\left(2-\sqrt{y}\right)+\sqrt{y}\left(2-\sqrt{y}\right)$
3

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

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

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

$4-2\sqrt{y}+2\sqrt{y}-y$
5
