Answer» Correct Answer - A I. ` x^(2) + 5x + 6 = 0` ` rArr x^(2) + 2x + 3x + 6 = 0` ` rArr x(x+2) + 3(x+2) = 0` ` rArr (x+3)(x+2) = 0` ` rArr x =- 3 or -2` II. ` y^(2) + 7y + 12 = 0` ` rArr y^(2) + 4y+3y+ 12 = 0` ` rArr y(y+4) + 3(y+4) = 0` ` rArr y =- 3 or -4 ` On comparing the value of equ. (i) and equ.(ii) ` x ge y` |
