As α=a and β=b
Now sum of zeroes = -(b)/a
or. α+β= -(b') /a
or. a+b = -(a) /1. .....As b'=a and a'=1
or. 2a+b=0.........(1)
Now product of zeroes = c/a
or. αβ =c/a
or. ab = b/1 ....as c=b and a'=1
or. a = b/b =1 ...... (2)
now putting 2 in 1 we have :
2(1) +b =0
b= (-2)
therefore the value of a =1 and b= (-2).
