The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.
Step-by-step explanation:
The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.
We have to find the roots of this given equation.
If a quadratic equation is of the form 
Its roots are
and 
Here the given equation is
= 0
a = 2
b = -4
c = -1
If the roots are
, then
= 
= 
= 
= 
= 
= 
These are the two roots of the equation.
Two sides are same so that would be isosceles triangle. So then you would add up all angles and get this equation: 180 = 38 + x + x
2x = 142
x = 71
So the value of x is 71.
D
Because it is the same while number just with a extra .9
