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