Question

we
we can find roots of quachatic equation if
b²_4ac<o​

Answer 1

if $b^{2} - 4 ac < 0$

  then it doesn't have real roots..................

for it we uses quadratic formula but our answer is not very good...........

qudratic formula =  $-+b \sqrt{b^{2} -4ac} / 2a$

hope this will helps u in ur studies..................
