Hi, I'm not quite sure how to do this. Could someone help me understand please?
Given positive integers x and y such that 2 x^2 y^2 + 4y^3 = 149 + 3x^2, what is the value of x+y?
I think I might have to factor parts of this different ways but I don't know how to get an equation where I could do that.
2x^2y^2 + 4y^3 = 149 + 3x^2 reaarange as
2x^2y^2 - 3x^2 + 4y^3 - 149 = 0
WolframAlpha does not show any integer solutions for x, y :
