Dear Student,
let one solution be m, then the other solution will be -m.
let third solution be n
sum of roots taken one at a time= m+(-m)+n= n = 2 -------- (A)
sum of roots taken two at a time = -m2 -mn+mn = -m2 = a ------(B)
product of roots = -m2n = -10------(C)
from A, B, C we get:
a= -5 .
Cheers!!
