hartnn · Answer

Do they want you to solve it using any specific method?

if not, try using the formula method

hartnn · Answer

Compare your quadratic equation with $ax^2+bx+c=0$
find $$a=...?\b=...?\c=...?\$$ $$ \ \sqrt{b^2-4ac}=...?$$
then the two roots of x are:
 $\huge{x_{1,2}=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}$

I know I am not supposed to have that answer lol ^^  is there another method like completeing the square or something?

hartnn · Answer

you'll get same answer with any method you use.

and yes, we can use completing the square method too. tried that before?

hartnn · Answer

though completing the square method will become complicated with fractions, 
if you can use, i recommend you use the formula
