Rewrite as .
Since both terms are perfect squares, factor using the difference of squares formula, where and .
Remove parentheses.
54/4.5 = 12
Set it up as long division, with 54 "inside" the division sign and 4.5 outside. Then you have to move the decimal on 4.5 to the right once, which will give you 45 on the outside. You also have to move the decimal over 1 more place on the 54, which will give you 540 on the inside. Then figure out how many times 45 can go into 54, which is once. Then subtract 45 from 54, which will give you 9. Then you are left with 90 on the inside and 45 goes into that 2 times.
