Answer 4

First you'd have to make the original problem equal zero. And then use the quadratic formula. \[\frac{ -b + or -\sqrt{b ^{2}-4ac} }{ 2a}\]

Answer 5

Do you get how to do those?

Answer 6

yes i get how to do it but i get confused when i get to the end of the equation

Answer 7

So youd have 3 + or - sqrt[-3^2 - 4(1)(8)] all over 2.
Which simplifies to 3 + or - sqrt(9-32) all over 2.
3 + or - sqrt-23 over 2 right? the i would come out so the 23 wouldn't be negative

Answer 8

So you'd have the second choice. Does that make sense?

Answer 9

yes can u help me with some more?
