Answer:

x^{2} + 8x + 11 = 0

Step-by-step explanation:

   \frac{x+2}{x+5} + \frac{x+6}{x+3} = \frac{7}{2}

\frac{(x+2)(x+3) + (x+6)(x+5)}{(x+5)(x+3)} = \frac{7}{2}

\frac{x^{2}+5x + 6 + x^{2} + 11x + 30 }{x^{2} + 8x + 15} = \frac{7}{2}

\frac{2x^{2} + 16x + 36}{x^{2} +8x + 15} = \frac{7}{2}

\frac{2(2x^{2} + 16x + 36)}{7(x^{2} +8x + 15)} = 1

\frac{4x^{2} + 32x + 72}{7x^{2} +56x + 105} = 1

4x^{2} + 32x + 72 = 7x^{2} +56x + 105

7x^{2}  - 4x^{2}  + 56x - 32x + 105 - 72 = 0

3x^{2} + 24x + 33 = 0

x^{2} + 8x + 11 = 0
