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.
