Answer 2

Let's solve the inequality step by step:

Step 1: Expand both sides of the inequality. (a + 3)(a - 5) > (a - 7)(a + 5) a^2 - 5a + 3a - 15 > a^2 + 5a - 7a - 35

Step 2: Combine like terms on both sides of the inequality. a^2 - 2a - 15 > a^2 - 2a - 35

Step 3: Subtract a^2 - 2a from both sides to eliminate the quadratic term. -15 > -35

Since -15 is greater than -35, the inequality is true for all values of 'a.' In other words, the inequality holds true regardless of the value of 'a.'
