Answer:
Presumably you're solving for x here? Without further information we'll assume that.
With that in mind, x is approximately equal to 0.86 and -0.46
Step-by-step explanation:
Let's start by putting it in the usual ax² + bx + c format.

let's solve it. First we'll multiply both sides by five, making the first term a perfect square:

Now we'll add 11 to both sides:

Which makes the left side a perfect square:

And now we can solve for x:

Note that there's no apparent way of drawing the ± symbol when editing equations, so take that + sign as actually being ±.
That gives us two answers:
