Solution 1
To solve this problem, we can use the given equations and algebraic manipulation.
- Start with the equation a^2 - b^2 = 36.
- Notice that this equation can be factored as (a + b)(a - b) = 36.
- We are also given that a + b = 4.
- Substitute this value into the factored equation: (4)(a - b) = 36 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
