Answer 1

Step-by-step explanation:

For the equation : 5x² - 7x + 1 ,

sum of roots = -(-7/5) = 7/5

product of roots = 1/5

1/a + 1/b

= (a+b) / ab

= sum of roots / product of roots

= (7/5) / (1/5)

= 7

So, the answer is 7

PLEASE MARK AS BRAINIEST

Answer 2

sum of roots is 7/5

product of roots is 1/5

then a+b/ab=7/5/1/5=7
