b) $\frac{2 x+10}{x^{2}-4 x+4}+\frac{x^{2}-25}{x-2}$

Step 1 ：Given the expression: \(\frac{2 x+10}{x^{2}-4 x+4}+\frac{x^{2}-25}{x-2}\)

Step 2 ：Factorize the numerator and denominator of each fraction.

Step 3 ：Simplify the expression by cancelling out common factors if any.

Step 4 ：The expression simplifies to: \(\frac{x^{3} - 2x^{2} - 23x + 60}{x^{2} - 4x + 4}\)

Step 5 ：This is the simplest form of the expression.

Step 6 ：Final Answer: \(\boxed{\frac{x^{3} - 2x^{2} - 23x + 60}{x^{2} - 4x + 4}}\)
