### Difficult Problems

1

Solved example of algebra

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

The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: $(a+b)(a-b)=a^2-b^2$, where:

• The first term ($a$) is $2$.
• The second term ($b$) is $\sqrt{y}$.
Then:

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

Calculate the power $2^2$

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

Cancel exponents $\frac{1}{2}$ and $2$

$4-y$

$4-y$
