Question

if d<0 the quadratic equations has two different real roots​

Answer 1

Answer:

If the discriminant is equal to zero, this means that the quadratic equation has two real, identical roots. Therefore, there are two real, identical roots to the quadratic equation x2 + 2x + 1. D > 0 means two real, distinct roots. D < 0 means no real roots.

Answer 2

$\huge\bf\underline\purple{Explanation:}$

The given statement is false Because If d<0 Then roots are complex and conjugate to each other

NATURE OF ROOTS:-

If D>0 Roots are real and distinct

If D<0 Roots are Complex and conjugate to each other

If D =0 Roots are real and equal

____________________________________________

So the given statemnet is false We can find out nature of roots with help of discriminnat only
