Answer:

[tex]\frac{x^2}{9}[/tex] - 4x + 36

Step-by-step explanation:

([tex]\frac{x}{3}[/tex] - 6)² = ([tex]\frac{x}{3}[/tex] - 6)([tex]\frac{x}{3}[/tex] - 6)

Each term in the second factor is multiplied by each term in the firs t factor, that is

[tex]\frac{x}{3}[/tex]([tex]\frac{x}{3}[/tex] - 6) - 6([tex]\frac{x}{3}[/tex] - 6)

Distribute both parenthesis

= [tex]\frac{x^2}{9}[/tex] - 2x - 2x + 36 ← collect like terms

= [tex]\frac{x^2}{9}[/tex] - 4x + 36
