Answer-I. y² + y – 56 = 0 II. 2x² + 11 x – 40 = 0

I. y y 56 0 y 8y - 7y 56 0 y y 8 7y 8 0 y 7, - 8 II. 2x 11 x 40 0 2x - 5 x 16x 40 0 x 2 x 5 8 2x 5 0 x 8 2 x 5 0 x - 8, 52 Hence, relationship cannot be established between x and y Alternate Method Remember whenever roots of x y are - both, there is no need to find the exact value of roots. In this case, there will be always no relation between x y. Hence relationship between x y cannot be established.
