We can find the roots of a quadratic equation with the quadratic formula

$x =\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$

For 1^{st }equation

$x =\frac{-5 \pm \sqrt{25-24}}{12}$

$x =\frac{-5 \pm 1}{12}$

$x =-0.5,-0.33$

For 2^{nd} equation

$15y^{2}+8y+1$=0

$15y^{2}+3y+5y+1$

y=$y=- \frac{1}{5} , -\frac{1}{3}$

(We can also find the roots by same method used for 1^{st} equation.)

$y=- 0.2 , -0.33$

Here,

$- 0.2 \ , \ -0.33 \ \geq -0.5 \ , \ -0.33$

Hence relation between x and y = $y \geq x$

Hence,Option $(B) x\leq y .$ is the correct choice.
