Answer 3

It seems to me that they want you to use the quadratic formula. Do you know what that is?

Answer 4

not really. i missed a lot and have a bunch of stuff due that i didn't learn i have to blast through all of it or i'm gonna fail. @LegendarySadist

Answer 5

Wait is the x2 supose to be x to the power of 2
if so woooops

Answer 6

Basically how the quadratic formula works is that for \[\large \sf ax^{2}+bx+c=0\],\[\large \sf x=\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}\]

Answer 7

So how to solve your question is this:
1. Get the 24 over to the left side.
2. Identify what the a, b, and c are in terms of the formula.
3. Enter a, b, and c into the quadratic formula.
4. Solve until you have the answer you are looking for.
