Answer:(A+7)(A−7)

Explanation:

Since both terms are perfect squares, factor using the difference of squares formula, a2−b2=(a+b)(a−b) where a=A and b=7.

Answer:

7.

Explanation:

To solve the equation a^2 - 49 by factoring, we can use the difference of squares formula. The difference of squares formula states that a^2 - b^2 can be factored as (a + b)(a - b).

In this case, a^2 - 49 can be rewritten as (a + 7)(a - 7).

By setting each factor equal to zero, we can solve for a:

a + 7 = 0

a = -7

a - 7 = 0

a = 7

Therefore, the solutions to the equation a^2 - 49 = 0 are a = -7 and a = 7.
