The expression in the image is a mathematical fraction with two different parts in the numerator and the denominator.

The numerator is:
$(a + b)^2 - c^2$ The denominator is: $(c - a)^2 - b^2$

Step-by-Step Solution:

1. Simplify the Numerator

The numerator is $(a + b)^2 - c^2$, which is a difference of squares. We can factor this as: [ (a + b)^2 - c^2 = [(a + b) - c][(a + b) + c] ] So the numerator becomes: $(a + b - c)(a + b + c)$

2. Simplify the Denominator

The denominator is $(c - a)^2 - b^2$, which is again a difference of squares. We can factor this as: [ (c - a)^2 - b^2 = [(c - a) - b][(c - a) + b] ] So the denominator becomes: $(c - a - b)(c - a + b)$

The Final Simplified Expression:

Thus, the given expression simplifies to: $\frac{(a + b - c)(a + b + c)}{(c - a - b)(c - a + b)}$
