Answer 2

Where are you having trouble using the quadratic formula @DragonFlame ?

Answer 3

-6.6 -1.4

Answer 4

you just need to use \[-b \pm \sqrt{b^2-4ac}\div2a\]

Answer 5

\[\huge x = \frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]

Answer 6

a=1 b=9 c=10

Answer 7

@Kainui I don't know how to put abc into the formula

Answer 8

so you get\[-9\pm \sqrt{81-4(10)}\div \]

Answer 9

2a

Answer 10

So just / by 2?
