Answer 2

To simplify the expression:

A^2 - 14a + 49 / (a^2 * a^2 / (a^2 - 49))

First, factor the numerator and denominator to simplify:

Numerator: A^2 - 14a + 49 factors to (A - 7)^2. Denominator: a^2 - 49 factors to (a + 7)(a - 7).

Now, rewrite the expression:

[(A - 7)^2] / [a^2 * a^2 / ((a + 7)(a - 7))]

Next, you can multiply the numerator by the reciprocal of the denominator:

[(A - 7)^2] * [((a + 7)(a - 7)) / (a^2 * a^2)]

Now, let's simplify further by canceling common factors:

[(A - 7)^2] * [((a + 7)(a - 7)) / (a^2 * a^2)] [(A - 7)^2] * [(a + 7)(a - 7)] / (a^2 * a^2)

So, the simplified expression is [(A - 7)^2 * (a + 7)(a - 7)] / (a^2 * a^2).
