Should we have a secular rational division of holidays and divide the circle of the year into 4 exact quarters?

Divide using long division: (x^3 + x^2 + 2x - 4) / (x-1)?

• x^2 + 2x + 4 x^2 + x - 4 x^2 + 4

• Answer:

  What they are telling you here is that (x-1) is a factor of x^3 + x^2 + 2x -4 work it out (x-1) ( x^2 + 2x + 4) = x^3 + x^2 + 2x -4 ( multiply it out and you'll see that is right). so if you divide this by (x-1) you get x^2 + 2x + 4
