    Explanation:

    X2 -5X + 6 = 0

    ⇒ X2- 3X -2X + 6 = 0

    ⇒ X(X - 3) - 2(X - 3) = 0

    ⇒ (X -3)(X -2) = 0

    ⇒ X = +3, +2

    2y2 – 7y +3 = 0

    ⇒ 2Y2− 6Y − Y + 3 = 0

    ⇒ 2Y(Y − 3) −1(Y − 3) = 0

    ⇒ (2Y − 1)(Y − 3) = 0

    ⇒ Y = 3, 0.5

    Hence, No relation can be established.
