anonymous · Answer

b^-4ac= 81-4x1x10 =1
hence two different rational solutions

anonymous · Answer

calculate b^2-4ac
if it is positive then you have two distinct roots
if it is zero then you have two identical roots
if it is negative then you have two imaginay roots

anonymous · Answer

so its the third one then? @irshadno1

anonymous · Answer

yes correct

anonymous · Answer

ok, awesome!!

anonymous · Answer

b^-4ac= 81-4x1x10
           = 81- 40 = 41

it is positive so you have two distinct roots

anonymous · Answer

ok, what does that mean?

anonymous · Answer

yes u r right ....
