Someone help me this... ​

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing 

Answerthe distance to nearby stars;

Ithink the answer is bhope this !

It took me a while to figure out this complex expression but i believe the answer you’re looking for is

but i am not sure because i am not at that level of math yet.
