### Answer

**Your input: simplify $$$\frac{\left(5 \sin^{2}{\left(x \right)} + 5 \cos^{2}{\left(x \right)}\right) \left(x^{2} + 4 x + 3\right)}{x^{2} + 8 x + 7}$$$**

**Answer: $$$\frac{\left(5 \sin^{2}{\left(x \right)} + 5 \cos^{2}{\left(x \right)}\right) \left(x^{2} + 4 x + 3\right)}{x^{2} + 8 x + 7}=\frac{5 x + 15}{x + 7}$$$**
