The general formula of quadratic equation is ax²+bx+c=0
comparing with general form we get:
1)sum of roots : -b/a
-0/1
product of roots: c/a
-3/1=-3
2) sum of roots: -b /a
-0/1
product of roots: c/a
-5/1=-5
3) sum of roots:. -b/a
-8/4=-2
product of roots: c/a
0/4
4) sum of roots: -b/a
-(-8)/2
8/2 =4
product of roots: c/a
6/2=3.
5) sum of roots: -b/a
-3/3=-1
product of roots : c/a
0/3
