Comment upon the nature of the roots without solving 1.). X​​​​​​2 - as - b​​​​​​2 = 0 When I solved the equation I got the roots as A​​​​​​2 + 4b2 But the answer is given as the roots are positive so it is real and unequal how is it? And why is it? A's value can be a negative no also like a= -3 So how can this be possible?

Comment upon the nature of the roots without solving

1.). X​​​​​​2 - as - b​​​​​​2 = 0

When I solved the equation I got the roots as

A​​​​​​2 + 4b2

But the answer is given as the roots are positive so it is real and unequal how is it? And why is it?

A's value can be a negative no also like a= -3

So how can this be possible?
