Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!
first you can see that you can divide it by 3 and put everything to the left hand side to get 3a^2-a-10=0
now you can factor it or just use the formula for quadratic expressions

complete squares is easiest
\(9a^2 - 30 =3a ;\) +30, -3a, /9 \[9(a^2 -{1\over3}a) = 30 \] \(9(a-{1\over6})^2 = 30 +{9\over36}\); /9 \[a-{1\over6} = \pm \sqrt{{10\over3} +{1\over36}}\] \[a = {1\over6} \pm {\sqrt{13}\over6}\] maybe lol
the latex slows me down
