Answer 1

Answer:

the nature of the roots are unreal.

Step-by-step explanation:

Given :

{x}^{2} - 5x + 7 = 0x

2

−5x+7=0

comparing x²-5x+7=0 with ax²+bx+c=0

we get,

a=1

b=-5 and

c=7

the formula of discriminant is

Discriminant= b²-4ac

=

{ - 5}^{2} - 4 \times 1 \times 7−5

2

−4×1×7

25 - 2825−28

-3.

we know that,

If the discriminant<0 , then the nature of the roots are unreal.

thus,

The nature of the roots are unreal.
