Answer:

Calculate the discriminant you will get k^2-4<O

this implies

k<+or-2

you observe that when k = -3 the answer k is less than -2 gets neglected therefore

k can have any value less than 2 and greater than -2 .

Answer:

Step-by-step explanation:

Conparing with ax²+bx+c=0

Here, a=1 b=k c=1

D=b²-4ac

=k²-4(1)(1)

=k²-4

For non real roots

D<0

=>k²-4<0

=>k²<0

=>k<4

=>k<2or -2

So k is < +2 or -2

So k can have any value smaller than 2 and greater than-2
