Please solve! grammer really easy!

Information on the cost of things, quantitative data has to do with numbers, qualitative data uses details such as taste, appearance, what it looks like etc. 

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 

Honestly i have no i guess the creators didnt think of that
