Please can I have the workings too

Answer:
[tex]\frac{3-2a}{a^2}[/tex]
Step-by-step explanation:
Before we can subtract the fractions we require them to have a common denominator.
Multiply the numerator/ denominator of [tex]\frac{2}{a}[/tex] by a , then
[tex]\frac{3}{a^2}[/tex] - [tex]\frac{2a}{a^2}[/tex] ← with common denominator a²
Add numerators leaving the denominator
= [tex]\frac{3-2a}{a^2}[/tex]
