Answer 2

To simplify the fraction (k^2 - 14kt + 49t^2) / (3k^2 - 21kt), we can first factor the numerator and denominator, and then cancel out any common factors.

1. Factor the numerator: k^2 - 14kt + 49t^2 can be factored as (k - 7t)^2.

2. Factor the denominator: 3k^2 - 21kt can be factored as 3k(k - 7t).

Now the fraction becomes [(k - 7t)^2] / [3k(k - 7t)].

3. Cancel out common factors: We notice that both the numerator and denominator have a common factor of (k - 7t). We can cancel it out to get the simplified fraction:

(k - 7t)^2 / (3k(k - 7t)) = (k - 7t) / (3k).

So, the simplified form of the fraction is (k - 7t) / (3k).
