The data type Type and its friends
GHC's compiles a typed programming lanuage, and GHC's intermediate language is explicitly typed. So the data type that GHC uses to represent types is of central importance.

prove that any number that is a square must have one of the following for its units digit: 0,1,4,5,6,9.
Consider a two digit number with unit digit as a and tens digit as b So a and b both are positive interger less than 10 So number can be written as 10b + a Now $(10b + a)^2 = 100b^2 + 20ab + a^2$ Now

how do you find the x-intercepts if you have 0 = x^3 -9x^2 + 15x + 30
I assume you mean "if you have $y= x^3- 9x^2+ 15x+ 30$" so the x-intercepts are where y= 0: $x^3- 9x^2+ 15x+ 30= 0$. Of course, you find them by solving that equation. I recommend crossing your
