Question

if B square-4ac less than 0 in ax square+bx+C=0 then what can you say about the roots of the equation​

Answer 1

Explanation :-

Condition:-

For any quadratic equation ,if it's discriminant -

• Discriminant (D) > 0

Hence, its roots are real and unequal.

• Discriminant (D) =0

Hence, its roots are real and equal.

• Discriminant (D) < 0

Hence, its roots are Imaginary.

• Discriminant (D) > 0 and be a perfect square,

Hence, its roots are real ,rational and unequal.

Solution :-

We know that,

$\: \bf{ Discriminant \: (D) = {b}^{2} - 4ac}$

According to the question,

It's discriminant is less then zero.

Hence,

The nature of roots is Imaginary.
