    I'm not sure but I'll try - I think it might go like this.

    When converting from x^2+10x+32 to the form of (x+#)^2 + # you have to take the middle number which in this case is 10. You divide it by 2, which is 5, then you square that answer (5)^2

    ur original form was standard form, and the middle number is called "b" - so the rule is to change from standard form to that new form you need to do this (b/2)^2

    That's where the 25 comes from - once you have the 25 you can actually convert the form to that new form.
