Question

dy/dx + 2/((x+1)^2)*y=(x+1)^3

Answer 1

I guess you're solving a differential equation?

Answer 2

find u(x):
\[\huge e ^{\int\limits_{}^{}\frac{ 2 }{ (x+1)^{2} }}\]
and multiply the equation by it... the left side will then be
( y * u(x) ) '
integrate both sides and divide by u(x)

Answer 3

(method of the "integrating factor")
