114.425<114.58 because 425<580.
The easiest way to reach this solution is to look at the numbers. Everything before the decimal point is the same, but the first digit after the place holder differs, one is four tenths and the other is 5 tenths. 4 is less than 5 making the first statement the correct one!
This is a simple formula:(a-b)*(a+b)= a^2-b^2
And it goes like this for your example: (a-1)*(a+1)=a*a+a-a-1*1=a^2-1^2=a^2-1
