1)5,-1,3
x-5=0 x+1=0 x-3=0
(x-5)(x+1)(x-3)=0
x%5E%283%29-7%2Ax%5E2%2B7%2Ax%2B15=0
...
2) 1,7,-5
x-1=0 x-7=0 x+5=0
(x-1)(x-7)(x+5)=0
x%5E%283%29-3%2Ax%5E2-33%2Ax%2B35=0
...
3)-1,1,-6
x+1=0 x-1=0 x+6=0
(x+1)(x-1)(x+6)=0
x%5E%283%29%2B6%2Ax%5E2-x-6=0
...
4) 2,-2,-3
x-2=0 x+2=0 x+3=0
(x-2)(x+2)(x+3)=0
x%5E%283%29%2B3%2Ax%5E2-4%2Ax-12=0
