\(\left|difference\;\;of\;\;roots\right|=\left| [{-b + \sqrt{b^2-4ac} \over 2a}]-[{-b- \sqrt{b^2-4ac} \over 2a}]\right|\)

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
