Question

if alpha and beta are the zeros of the polynomial 5 x square - 7 x + 2 the sum of their reciprocal is​

Answer 1

Answer:

hope this helpful

Step-by-step explanation:

5x²-7x+2

5x²-5x-2x+2

(5x²-5x)-(2x-2)

5x(x-1)-2(x-1)

(x-1)(5x-2)=0

x-1=0,5x-2=0

x=1,x=2/5

alpha=1 and beta=2/5

1+1/2/5

1+5/2

2+5/2

7/2

hence the sum of reciprocal of zeroes is 7/2
