# Q: Homework - Past exam solution Is this the right solution?

I am trying to find Vo but I am not sure If this solution right? Is there a shorter path to find Vo?

solution

I think I found what is going wrong (I wish to be the only mistake) I made a mistake in multiplication in the second line of the third photo it is not : $$s^{2}*V2$$ but $$s^{3}*V2$$
$$V2 = \frac{-605 + 7.5\ast s + s^{2}}{-12.5\ast s-3\ast s^{3}}$$
