A triangle has two sides of length 13 and 10. What is the largest possible whole-number length for the third side?
NeTakaya

In order for a triangle to exist, the two smaller sides must add to a number greater than the largest side.


So, 13+10 = 23

So, the number has to be smaller than 23, and the largest whole number less than 23 is 22.


22 Is the largest possible whole number.

What is the solution set of the quadratic equation 8x2 +2x +1 =0?
Sidana [21]
   
\displaystyle\\
 8x^2 +2x +1 =0\\\\
x_{12}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}=\frac{-2\pm \sqrt{2^2-4\cdot 8 \cdot 1}}{2\cdot 8}=\\\\
=\frac{-2\pm \sqrt{4-32}}{16}=\frac{-2\pm \sqrt{-28}}{16}=\frac{-2\pm \sqrt{4\cdot 7\cdot(-1)}}{16}=\\\\
=\frac{-2\pm 2i\sqrt{7}}{16}=\frac{-1\pm i\sqrt{7}}{8}= -\frac{1}{8}\pm  \frac{\sqrt{7}}{8}i\\\\
x_1 =   \boxed{-\frac{1}{8}+  \frac{\sqrt{7}}{8}i}\\\\
x_2 =   \boxed{-\frac{1}{8}-  \frac{\sqrt{7}}{8}i}\\\\
x_1,~x_2~\in \mathbb{C}
