Question

Find whether the quadratic equation x^2-x+2=0 has real roots or not.if yes, find the roots .

Answer 1

The given equation is x2 - x + 2 = 0

We have a = 1  ;  b = -1  ; c = 2

Now, D = b2 - 4ac = (-1)2 - 4(1)(2) = 1 - 8 = -7 < 0

Since, D<0, so the given equation has no real roots.

Answer 2

Answer:

D<0 it is not real roots....
