c1 = x(1-x) c2 = 4x(1-x) The Vector field F is given by F(x,y) =((x+y), (X^2 + y)

to find Integral of F in respect to c1 do i just put x= x+y into c1 then integrate or am i making it too simple?

and C is the curve going along c1 then c2, how do i find the integral of F in respect to C do i just add them together?
