  dy/dt = 1 + t^2 + y^2 + (t^2 x y^2)

  how to make all the y terms together and the t terms together? tried to solve it using variable separable method but my answer is incorrect

  is it dy / (2+ 2y^2) = dt / t^2 ?

  1 + t ² + y ² + (t ² y ²)

  = (1 + t ²) + y ²(1 + t ²)

  = (1 + t ²)(1 + y ²)

  Can?
