This is incorrectly labeled "Sentence Correction." Relabel it, and I'll be happy to post a reply.

we know sum of roots = (-b/a) and product of roots = c/a

so here now a =1, b = 8 and c =15
s+r = -8/1
s*r = 15/1

(s-r)^2 = (s + r)^2 - 4(s*r) ==> (-8)^2 -(4*15) ==> 64 -60==>4

s-r = 2

option c

hey sana.noor, can you tell me how do you have a tag line in every post. I'm referring to this "If you found my Post really helpful, then don't forget to click the Thank/follow me button. Smile"
