Find the general solution two ways. First use an integrating factor and then use separation of variables.y' = 
A. Integrating factor: I(x) = 
Separation of variables: 
dy = 
dx
General solution: y = C(x2 + 1) + 3
B. Integrating factor: I(x) = 1 + x2
Separation of variables: (3 + y) dy = 2x(1 + x2) dx
General solution: y = C(x2 + 1) - 3
C. Integrating factor: I(x) = 
Separation of variables: 
dy = 
dx
General solution: y = C(x2 + 1) - 3
D. Integrating factor: I(x) = 1 + x2
Separation of variables: (3 + y) dy = 2x(1 + x2) dx
General solution: y = C(x2 + 1) + 3
