Answer:

Area is (x² - 9) units squared.

Step-by-step explanation:

• from difference of squares quadratic property:

[tex]{ \boxed{ \rm{(a - b)(a + b) = ( {a}^{2} - {b}^{2}) }}}[/tex]

→ a is x

→ b is 3

• Therefore:

[tex]{ \tt{area = {x}^{2} - {3}^{2} }} \\ \\ { \tt{area = {x}^{2} - 9 }}[/tex]
