Question

b2-4ac< 0 then roots of quadratic equation is not ..... number
fill the blank.​

Answer 1

Step-by-step explanation:

Discriminant (D) = b^2 - 4ac

if D > 0 roots are real and distinct

if D = 0 roots are real and equal

else if D < 0 roots are imaginary (complex ) or not real

So the answer to your question is that roots are imaginary and hence NOT REAL
