Answer:

A matches with P

Step-by-step explanation:

Roots of x^2-x+1 have to be found.

Using quadratic formula

Solution of quadratic equation( ax2+bx+c=0) is given by -

x=(−b±(b2−4ac)^0.5)/2a . . . (1)

Here, a = 1, b = -1 and c = 1  (x2+x+1=0)  

Just put the value of a, b and c in eq(1),

x=1±(1−4∗1∗1)/2∗1  

x=(1±−3^0.5)/2  

This is shows its have only imaginary roots.

ROOTS Are

1±(-1.732)/2

or  

1.366  or  0.366

Taking in the first option,

1.366^2  + 0.366^2 ----->1.978 or can be rounded to 2....

As you substitute these roots in other probable answers, can be matched to others

Since this is true, A matches with P.
