Answer 1

Answer:

b=7

Step-by-step explanation:

The given algebraic expression, a quadratic binomial, x² - 49 = x² - 7² , falls into the pattern of the "Difference of Two Squares": a² - b² = (a + b)(a - b), where, in this case, a = x and b = 7.

Substituting, we have:

a² - b² = (a + b)(a - b)

x² - 7² = (x + 7)(x - 7) is the original algebraic expression, x² - 49, factored.

Note: To factor the given expression, x² - 49, and those like it, you need to be able to recognize it as the "Difference of Two Squares".
