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
