Question

if alpha and beta are the zeroes of the polynomial f(x)=ax^2+bx+c,then the value of 1/alpha+1/beta
please explain how the answer comes don't just write answer

Answer 1

Answer:

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

Answer 2

Answer:- The value is -b/c

Step-by-step explanation:let alpha =x;and also beta =y .....(for better understanding) then ax2+bd+c let's see........ 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 now hence Answer is:-b/c.
