Teachers state that the circumference of a circle is 2*pi*r. However, pi is irrational, so therefore so is the circumference of a circle, so can we ever know the circumference of a circle?

2x^2 - 5x + 11 = 2[(x - 5/4)^2 - 25/16 + 11/2]
= 2[(x - 5/4)^2 + 63/16]
= 2[(x- 5/4)^2 + 63/8

I understand the top line of this equation but the rest confuses me! Can someone explain how to get from 25/16 + 11/2 then to 63/16 and to 63/8 in the last line. Thanks!
