Evaluate the integral s(5x^3+3x^-2-7x^-5+2)dx?

Let $ = Integral note that something related to the derivative of the bottom appears in the top $ dx(x)/(7x^2+3)^5 let u=7x^2+3 du=14x dx = 1/14 $ 14x dx u^(-5) = 1/14 $ u^(-5) du = 1/14 1/(-4) u^(-4) = -1/56(7x^2+3)^4 + C.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
