Answer:
x = -3 , - 15
Step-by-step explanation:
<em>Given:</em>
<em>x² + 18x + 45 = 0</em>
<em>Solve:</em>
<em />![x_{1,\:2}=\frac{-18\pm \sqrt{18^2-4\cdot \:1\cdot \:45}}{2\cdot \:1}](https://tex.z-dn.net/?f=x_%7B1%2C%5C%3A2%7D%3D%5Cfrac%7B-18%5Cpm%20%5Csqrt%7B18%5E2-4%5Ccdot%20%5C%3A1%5Ccdot%20%5C%3A45%7D%7D%7B2%5Ccdot%20%5C%3A1%7D)
Simplify
![-18\pm \sqrt{18^2-4\cdot \:1\cdot \:45=12](https://tex.z-dn.net/?f=-18%5Cpm%20%5Csqrt%7B18%5E2-4%5Ccdot%20%5C%3A1%5Ccdot%20%5C%3A45%3D12)

Separate the solution
![x_1=\frac{-18+12}{2\cdot \:1},\:x_2=\frac{-18-12}{2\cdot \:1}](https://tex.z-dn.net/?f=x_1%3D%5Cfrac%7B-18%2B12%7D%7B2%5Ccdot%20%5C%3A1%7D%2C%5C%3Ax_2%3D%5Cfrac%7B-18-12%7D%7B2%5Ccdot%20%5C%3A1%7D)
