Here you seem to say that the integral of x²/2 is x. That is however not the case. In step one we saw that the Integral of x is x²/2 however the opposite is not true. So that is the first mistake that breaks your whole process, I believe You can't just multiply in and out of integrals that's not how they work. Even if x was the integral of x²/2 dividing by it would give you 1 = (1/x) times Integral x²/2, not Integral of x/2 Same problem and continuing from a false premise. Same Here you suddenly remember the integral again though you disregarded it before. You also miss the constant again. And that's why this is wrong. __________________

You can't just "divide" by dx, that's not an operation that makes any kind of sense.
