Answer:
![x=-2.38](https://tex.z-dn.net/?f=x%3D-2.38)
![x=-4.62](https://tex.z-dn.net/?f=x%3D-4.62)
Step-by-step explanation:
The question is ![(2x+3)^2+8(2x+3)+11=0](https://tex.z-dn.net/?f=%282x%2B3%29%5E2%2B8%282x%2B3%29%2B11%3D0)
<em>We let
, so the equation becomes:</em>
![u^2+8u+11=0](https://tex.z-dn.net/?f=u%5E2%2B8u%2B11%3D0)
Where ![a=1, b=8, c=11](https://tex.z-dn.net/?f=a%3D1%2C%20b%3D8%2C%20c%3D11)
Putting it in the quadratic formula, we have:
<u>Quadratic formula:</u> ![\frac{-b+-\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%2B-%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
Substituting we have: ![\frac{-8+-\sqrt{(8)^2-4(1)(11)} }{2(1)}\\=\frac{-8+-\sqrt{20} }{2}\\=\frac{-8+-2\sqrt{5} }{2}\\=-4+\sqrt{5}, -4-\sqrt{5} }](https://tex.z-dn.net/?f=%5Cfrac%7B-8%2B-%5Csqrt%7B%288%29%5E2-4%281%29%2811%29%7D%20%7D%7B2%281%29%7D%5C%5C%3D%5Cfrac%7B-8%2B-%5Csqrt%7B20%7D%20%7D%7B2%7D%5C%5C%3D%5Cfrac%7B-8%2B-2%5Csqrt%7B5%7D%20%7D%7B2%7D%5C%5C%3D-4%2B%5Csqrt%7B5%7D%2C%20-4-%5Csqrt%7B5%7D%20%7D)
