I. $5{x^2} + 17x + 6 = 0$

II. $2{y^2} + 11y + 12 = 0$

$;{f{I}}.;;5{x^2} + 17x + 6 = 0$

$5{x^2} + 15x + 2x + 6 = 0$

$5xleft( {x + 3} ight) + 2left( {x + 3} ight) = 0$

$x = - 3, - frac{2}{5}$

${f{II}}.;;2{y^2} + 11y + 12 = 0$

$2{y^2} + 8y + 3y + 12 = 0$

$2yleft( {y + 4} ight) + 3left( {y + 4} ight) = 0$

$y = - 4, - frac{3}{2}$

Hence, No relation
