Pls can I have the workings too

Answer:
[tex]\frac{(3-2a)}{a^2}[/tex]
Step-by-step explanation:
Given expression is,
[tex]\frac{3}{a^2}- \frac{2}{a}[/tex]
First equalize the denominators of the fractions,
[tex]\frac{3}{a^2}-\frac{2a}{a^2}[/tex]
Now combine the fraction as a single fraction,
[tex]\frac{(3-2a)}{a^2}[/tex]
Since, we can not solve this fraction further, this will be simplified form of the given expression.
