Question

Determine the nature of the roots of quadriatic equation:x^2-x+2=0​

Answer 1

Answer:

a = 1, b = – 1, c = 2

Discriminant: D = b2 – 4ac

= (– 1)2 – 4 x 1 x 2

= 1 – 8

= – 7 < 0

Equation has no real roots.

Answer 2

Step-by-step explanation:

x2 – x + 2 = 0 Compare given equation with the general form of quadratic equation, which is ax2 + bx + c = 0 a = 1, b = – 1, c = 2 Discriminant: D = b2 – 4ac = (– 1)2 – 4 x 1 x 2 = 1 – 8 = – 7 < 0Read more on Sarthaks.com - https://www.sarthaks.com/704474/find-the-nature-of-the-roots-of-thequadratic-equation-x-2-x-2-0
