Answer:

Explanation:
Algebra Simplifying
We are given the expression:

We need to repeatedly use the following identity:

For example, the first numerator has a difference of squares thus we factor as:

The first denominator can be factored also:

Applying the same procedure to all the expressions:

Simplifying all the fractions:

Since all the denominators are equal:

Simplifying:

Simplifying again:
T = 1
Thus:
