Question

The ratio of the sum and product of the roots of the equation 7x212x+18=0 is :
i) 7:12
ii) 7:18
iii) 3:2
iv) 2:3​

Answer 1

Ratio of sum of the roots and product of the roots = -b:c = 12:18=2:3
Hence iv is correct option

Answer 2

Answer:

iv) 2:3

Step-by-step explanation:

7x² - 12x + 18 = 0

We know that, every eqⁿ is written in the form, k[x² - (S)x + P]

So, in the given eqⁿ, Sum of Roots, S = 12/7

And, Product of Roots, P = 18/7

So, ratio of S & P = 12:18 = 2:3
