Math Problem Statement
One number is 55 more than another. The difference between their squares is 6565. What are the numbers?
Solution
Let the two numbers be and , where is 55 more than . Thus, we can write the relationship between the two numbers as:
We are also given that the difference between their squares is 6565, which leads to the equation:
Using the difference of squares formula:
Substituting into the equation:
This simplifies to:
Now, divide both sides by 55:
Solve for :
Now, substitute into the equation :
Thus, the two numbers are:
