1. a=1, b=6 c=8
sum of the roots: -b/a= -6
product of the roots: c/a= 8
2. a=2, b=4, c=-6
sum of the roots: -b/a= -2
product of the roots: c/a= -3
3. a=3, b=-5, c=2
sum of the roots: -b/a= 5/3
product of roots: c/a= 2/3
4. a=1, b=-7, c=6
sum of the roots: -b/a= 7
product of the roots: c/a= 6
hope it helps
