The blackboard contains two sections with mathematical equations and expressions.

I. a) \(3x^2 - 2x - 1 = 0\)

b) \(\frac{x^2 - 6}{x - 3} = \frac{x}{x - 3}\)

II. a) \(\)

b) \(\)

It looks like section II is not fully visible. If you have more questions or need solving for part I, feel free to ask!
