Answer:
1. a=1 b= -2 c= -8
sum of zeroes =-b/a =-(-2) /1=2
product of zeroes =c/a=-8/1= -8
verification:
let x²-2x-8=0
x²-4x+2x-8=0
x(x-4) +2(x-4) =0
(x-4) (x+2)=0
(x-4) =0 or (x+2)=0
x=4 or x=-2
sum of zeroes=4+(-2) =2
product of zeroes = 4×-2 =-8
like that you have to do that for all sums in 1st question
2. as per given alpha + beta =1/4 and alpha beta =-1
the polynomial
k(x²-x(alpha + beta) +(alpha beta))
k(x²-x(1/4)+(-1))
k(x²-x-1/4)
k(4x²-x-4/4)
if k=4 implis
the polynomial 4x²-x-4
