Question

If alpha and beta are zeroes of polynomial x√ -p(x+1) +c such that (alpha + 1 ) ( beta+1 )=0 find value of c

Answer 1

Step-by-step explanation:

let alpha = x and beta = y......... For better understanding

ax2+bx+c

x+y=-b/a.......1

x.y=c/a..........2

1/x +1/y= x+y/xy......cross multiplication

-b/a divided by c/a from 1 and 2

a gets cancelled hence

Answer is : -b/c
