(i)` 2x^(2)-17x+21 =0` (ii)` 5y^(2)-32 + 35 = 0`A. `x lt y`B. ` x gt y`C. x = y or no relation can be established between x and y.D. ` x le y`

Answer» Correct Answer - C
(i) ` 2x^(2) - 17x + 21 =0`
` 2x^(2) - 14x - 3x + 21 = 0`
` 2x(x-7) -3 ( x -7) = 0`
` (2x -3) (x-7) = 0`
` x = 3/2 , 7`
(ii) ` 5y^(2) - 32y+35 = 0`
` 5y^(2) - 25y - 7y + 35 = 0`
` 5y(y-5) -7(y-5) = 0`
`(5y-7) (y-5) = 0`
` y = 7/5, 5`
`:. ` No relation can be established between x and y
