1. ## last one! which formula do i use for this one?

The squares of two consecutive integers differ by 95. Find the integers.

For the 4th time:

Did you read the rules here?
that it's ok for us to do YOUR homework?

3. ## Re: last one! which formula do i use for this one?

im not even asking for you to do my homework. im just asking for the formulas so i can do the work on my own. and these are just practice problems for an upcomming exam

It's not a matter of "using a formula". To do this problem you need to think about what the words mean in terms of mathematics.

Call the smaller of the two numbers x, say. Since these are "consecutive integers", what is the other number equal to? How would you write their squares?
How would you write the difference of the two squares? Set that equal to 95 and solve the equation for x.

Why don't you attempt something and post it up. How about starting by letting x = one of the integers?
