They converted 432 in terms of multiples 12 & 6 so that it makes easy to cancel.

432/12=36 so 12*36 or 12*6^2=432.

Whenever there is a numerator in the form like (number) raised to something. Then Always try to bring denominator in the same form i.e. number (same as that of numerator) raised to something. So that the numbers can be easily cancelled out and our calculation becomes easier.
