Answer:
C
Step-by-step explanation:
The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)
So for this, you need to know the quadratic formula, which is:

<em>*ignore the weird capital A, it keeps coming up when i try to use the ± symbol</em>
They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that
comes first.
<u>So now we have the equation: 3</u>
<u> - 2x +1</u>
*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of
, b is always the coefficient of x and c is always the constant (number without an x)
<u>So, i can find that, in this case:</u>
a = 3 b= -2 c=1
<u>Now substitute each of those values it into the original quadratic equation:</u>
<u />

<em>*again, ignore the weird capital A. </em>
That's how you find the answer, which from what i can tell in the picture is C.
Hope that helped : )
