Comment upon the nature of the roots without solving 1.). X2 - as - b2 = 0 When I solved the equation I got the roots as A2 + 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? |
