How do I find all the integer solutions for $$x^3-y^3-2x^2=1$$ My attempt: I realized that the oddity between $x$ and $y$ need to be different. So I proposed that $x$ is odd and $y$ is even and tried substituting $x=2m+1$ and $y=2n$ and got this equation: $$4m^3+2m^2+m-4n^3=1$$ However, I wans’t able to get more progress. I also tried factoring and got this equation. This gave me $$(y+1)(y^2-y+1)=x^2(x-2)$$ So I found two integer pairs, $(0, -1), (2, -1)$. However, I cannot gurantee this is it. Please help me. Thank you!
