Question

Describe about the nature of roots for a quadratic equation.

Answer 1

if D is greater than 0 then nature of roots is real and distinct
if Dis equal to 0 then the nature of roots is two equal real roots
if D is smaller than 0 then the nature of roots is no real roots

Answer 2

Answer:

Step-by-step explanation:

If ax² + bx + c = 0 ,( a ≠ 0 ) is a

Quadratic equation.then

Discreminant ( D ) = b² - 4ac

Nature of roots :

i ) if D > 0 ,

then equation has real and

distinct.

ii ) if D = 0 ,

then the equation has real

and equal roots.

iii ) if D < 0,

Equation has no real roots .
