Step-by-step explanation:
Let the angle near point A be 
.
Let the angle near point B be 
.
Let the angle near point C be 
.
Let the external angle near point A be 
.
Let the external angle near point B be 
.
Let the external angle near point C be 
.
According to exterior angle property,exterior angle of an angle is the sum of other two angles.
So,
According to angle sum property,the sum of angles in the triangle add to 
We can plug those values into the equation, and if the answer is incorrect, we'll know if either one is extraneous.
√11 - 2(-7) = √(-7)^2 + 4(-7) + 4
√25 = √25
5 = 5
The first solution, -7, makes the equation true, and so it is not extraneous.
√11 - 2(1) = √(1)^2 + 4(1) + 4
√9 = √9
3 = 3
The second solution, 1, makes the equation true, and so it is also not extraneous.
<h3>The correct option is D, neither solution is extraneous. </h3>
