Question

what is the nature of roots of a uadratic equation x2-2x+4=0

Answer 1

Answer:

No real roots

Step-by-step explanation:

if: D>0 then real and unequal roots

D=0 then real and equal roots

D<0 then no real roots it means roots are imaginary

D= b^2-4ac

=2^2-4*1*4

= -12<0

means D<0

therefore, no real roots exists.

I hope it will helps you friend

Answer 2

x^2-2x+4=0

A=1, B= -2 and C=4

D=B^2-4AC

=(-2)^2-4(1)(4)

=4-16

= -12

As,D<0 it is has non real roots
