Question 1 of 10 2 points describe the nature of the roots of this equation. 2x2-x+1=0 o o o o a. two complex roots b. one real, double root c. two real, irrational roots d. two real, rational roots

explanation:

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
