Does anyone know how to finish it or did I do it right?? I’m confused if I have to cancel out the 6x and leave the 3 over x or leave it as it is.

Answer:
[tex] \frac{2x - 1}{2 {x}^{2} } [/tex]
Step-by-step explanation:
From your last step, divide by 3 throughout.
You cannot divide by 6x throughout because 3 cannot be divided by 6x.
Another way to do it is:
[tex] \frac{6x - 3}{6 {x}^{2} } \\ = \frac{6x}{6 {x}^{2} } - \frac{3}{6 {x}^{2} } \\ = \frac{1}{x} - \frac{1}{2 {x}^{2} } [/tex]
However, if the question requires you to leave your answer in a single fraction in its simplest form, only the first answer is accepted.
