Use the quadratic equation to solve this (image of the quadratic equation is below)
Remember that quadratic functions are set up like so:
To make the equation 3x² + 4x = -8 into a quadratic function you must bring -8 to the left side of the equation so it equals zero. To do this add 8 to both sides
3x² + 4x + 8= -8 + 8
3x² + 4x + 8 = 0
That means that in this equation...
a = 3
b = 4
c = 8
^^^Plug these numbers into the quadratic equation and solve (Keep in mind that +/- is ± )
^^^There is no real solution to this equation. You must have an imaginary solution

So your equation is 
. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's
right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be
0.36.
I hope I helped!
