4. If alphs and beta are the zeros of the quadratic polynomial pu) – 5y²- 7y+1, find the value of 1/alpha + 1/beta​

1. Answer:

   Step-by-step explanation:

   since αandβare zeros of polynomial p(x)=5y²- 7y+1 .

   sum of zeros ,α+β= -coefficient of y/coefficient of y²

   = -(-7)/5=7/5

   and,product of zeros,αβ=constant term/coefficient of y²

   =1/5

   now,we have

   1/α+1/β=α+β/αβ=(7/5)/(1/5)=7.is the right answer.

   mark me as brainliest…
