Question

The ratio of the sum and the product of the roots of $5x^2–14x+8=0$ is

• A. 5:8
• B. 7:4
• C. 6:5
• D. 9:11

Answer 1

The correct option is B

7:4

For, $5x^2–14x+8=0$

$\text{Sum of the roots}=-\frac{(-14)}{5}=\frac{14}{5}$

$\text{Product of the roots}=\frac{8}{5}$

Thus, sum of roots : product of roots is:
$\frac{14}{5}:\frac{8}{5}=14:8=7:4$
