Answer 2

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

Answer 3

now you can factor it or just use the formula for quadratic expressions

Answer 4

complete squares is easiest

Answer 5

\(9a^2 - 30 =3a ;\) +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
