1.

I.2x^(2) + 9x + 7 = 0""II. Y^(2) + 4y+4 = 0

Answer»

if`x gt y`
if`x GE y`
if `x LT y`
if x = y or no relationchip can be established.

Solution :I. ` 2X^(2) + 9x + 7 = 0`
` 2x^(2) + 7x + 2x + 7 - 0`
` x(2x+7)+1(2x + 7) = 0`
` (x+1) (2x + 7) = 0`
` x = - 1, - 7/ 2`
II. ` y^(2)+ 4y + 4 = 0`
` y^(2) + 2y + 2y + 4 = 0`
` y (y+2) +2(y+2) = 0`
` (y + 2) (y+2) = 0`
` y =- 2, -2`
` :. ` Norelation.
