Answer:
[tex]\frac{1}{5}[/tex] + [tex]\frac{9}{5x^2}[/tex]
Step-by-step explanation:
[tex]\frac{1}{5x}[/tex] × ([tex]\frac{4x^2}{4x}[/tex] + [tex]\frac{36}{4x}[/tex])
[tex]\frac{1}{5x}[/tex] × (x + [tex]\frac{9}{x}[/tex])
Opening the brackets gives:
[tex]\frac{1}{5}[/tex] + [tex]\frac{9}{5x^2}[/tex]
