Can you take it from there jxc?
You responded only after I complained on other posts, \
You posted this question afterwards.

How about you show us what you have already tried for yourself instead of just posting bare questions.
In fact please go to the link above. And explain to us how Textot got his answer.
If you do not know then ask Textot questions about it.
Encourage or even push him/her to guide you through it.
ok lemme get my paper...
\(\frac{-b+\sqrt{b^2-4ac}}{2a}-\frac{-b-\sqrt{b^2-4ac}}{2a}\Rightarrow \frac{-b+b+\sqrt{b^2-4ac}+\sqrt{b^2-4ac}}{2a}\Rightarrow\frac{2\sqrt{b^2-4ac}}{2a}\Rightarrow \frac{\sqrt{b^2-4ac}}{a}\Rightarrow \frac{\sqrt{61}}{3} \implies \boxed{a=3}\)
I might have explained it a little thinly on accident
