In the following question, two quadratic equations labeled I and II are provided. Solve both equations to determine the relationship between x and y.

I. x² - 7x - 260 = 0
II. y² - 3y - 54 = 0

The correct option is If x = y or no relation can be established.

To determine the relationship between x and y, we will solve each quadratic equation individually to find their respective roots, and then compare the roots with each other.

Step 1: Solve Equation I for x

The first quadratic equation is:

$x^2-7x-260=0$

We need to find two factors of -260 whose sum is -7. These numbers are -20 and +13.
Splitting the middle term, we get:

$x^2-20x+13x-260=0$

Factor by grouping:

$x(x-20)+13(x-20)=0$

$(x-20)(x+13)=0$

Equating each factor to zero:

$x-20=0\Rightarrow x=20$

$x+13=0\Rightarrow x=-13$

Thus, the roots for x are x = 20 and x = -13.

Step 2: Solve Equation II for y

The second quadratic equation is:

$y^2-3y-54=0$

We need to find two factors of -54 whose sum is -3. These numbers are -9 and +6.
Splitting the middle term, we get:

$y^2-9y+6y-54=0$

Factor by grouping:

$y(y-9)+6(y-9)=0$

$(y-9)(y+6)=0$

Equating each factor to zero:

$y-9=0\Rightarrow y=9$

$y+6=0\Rightarrow y=-6$

Thus, the roots for y are y = 9 and y = -6.

Step 3: Compare values of x and y

Comparing every root of x with every root of y:
1. For x = 20 and y = 9: x > y
2. For x = 20 and y = -6: x > y
3. For x = -13 and y = 9: x < y
4. For x = -13 and y = -6: x < y

Since x is greater than y in some cases and less than y in other cases, no consistent relationship can be established between x and y.

Conclusion:
Hence, the correct option is If x = y or no relation can be established.
