Dear Nehal,


{(x+9)(x+1)/(x+6)} - x ≥ 0


{(x+9)(x+1)-x(x+6)}/(x+6) ≥


Expanding and solving we get


(4x+9)/(x+6)≥0


or 4(x+9/4)/(x+6)≥0


or (x+9/4)/(x+6)≥0


By wavy curve method x belongs to (-∞,-6]U[-9/4,∞)

I dont think that the answer would be frm - infinity to 6 (including six)....because if we include six then denominator would become 0...hence the answer would be not defined......bt i can also be wrong....incase im wrong pls explain me the right answer
