The general formula for a equation of the form:
is:
![x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%7D%7B2a%7D)
In this case we notice that a=1, b=-4 and c=3. Plugging this values in the general formula we get:
![\begin{gathered} x=\frac{-(-4)\pm\sqrt[]{(-4)^2-4(1)(3)}}{2(1)} \\ =\frac{4\pm\sqrt[]{16-12}}{2} \\ =\frac{4\pm\sqrt[]{4}}{2} \\ =\frac{4\pm2}{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%3D%5Cfrac%7B-%28-4%29%5Cpm%5Csqrt%5B%5D%7B%28-4%29%5E2-4%281%29%283%29%7D%7D%7B2%281%29%7D%20%5C%5C%20%3D%5Cfrac%7B4%5Cpm%5Csqrt%5B%5D%7B16-12%7D%7D%7B2%7D%20%5C%5C%20%3D%5Cfrac%7B4%5Cpm%5Csqrt%5B%5D%7B4%7D%7D%7B2%7D%20%5C%5C%20%3D%5Cfrac%7B4%5Cpm2%7D%7B2%7D%20%5Cend%7Bgathered%7D)
then:
and
Therefore, x=3 or x=1.
Answer:
It's not a polygon
Step-by-step explanation:
Polygons are always 2D. This shape is 3D. Everything else is fine.

Have a nice day.
Step-by-step explanation:
right now but I have no idea how much that would have to be in the same place as last week and he said it would be a lot of people are coming to see you and the girls are doing well and
<span>7.71(–0.02)
</span><span>0.23(–1.1)
</span><span>–5.09(8.1)
The reason is because a negative * positive will always give a negative answer. Negative * negative and positive * positive will always have a positive answer.</span>
100 seats
<span>So guessing your supposed to have a even number of each seats that's 100 seats
