Answer 1

I got two choices I found, but not sure which is the right one.

Answer 2

Use the quadratic formula.

Answer 3

I think both solutions are the right one because quadratic equations have 2 solutions

Answer 4

\[x = \frac{ -3 \pm \sqrt{13} }{ 2 }\]
\[x = \frac{ 3 \pm \sqrt{13} }{ 2 }\]

Answer 5

I have to pick one.

Answer 6

Oh lol 4 solutions

Answer 7

The formula starts with -b and b = -3 so -(-3) = 3, the second set is the right one
