${x}^{2} - 0.36$

#### Explanation:

Given: $\left(x - 0.6\right) \left(x + 0.6\right)$

Use the fact that $\left(a - b\right) \left(a + b\right) = {a}^{2} - {b}^{2}$.

Here, $a = x , b = 0.6$.

$= {x}^{2} - {0.6}^{2}$

$= {x}^{2} - 0.36$

$\left(x - 0.6\right) \left(x + 0.6\right) = {x}^{2} - 0.36$

#### Explanation:

Use the Difference of Squares Identity $\left(a + b\right) \left(a - b\right) = {a}^{2} - {b}^{2}$

$\left(x - 0.6\right) \left(x + 0.6\right) = {x}^{2} - 0.36$
