Answer 2

To solve the given expressions, let's take them one at a time:

1. c² - 10c - 252:

To factorize this quadratic expression, we need to find two numbers whose product is -252 and whose sum is -10. The numbers are -18 and 14. So we can write the expression as:

(c - 18)(c + 14)

Therefore, the factored form of the expression c² - 10c - 252 is (c - 18)(c + 14).

2. 49 - a²:

This expression represents the difference of squares. It can be factored using the formula a² - b² = (a + b)(a - b). In this case, a = 7 and b = a. Applying the formula, we have:

49 - a² = (7 + a)(7 - a)

Therefore, the factored form of the expression 49 - a² is (7 + a)(7 - a).
