Question

Accepted Answer

Correct answer: D. (d) : Given, (3x+12x-1x+25x-13x+2x+17x-23x+14x-1) To find the constant term, putting x=0, we get (1-12-121-21-1) =1 (-2-1 )+1 (1+2 )+2 (-1+4 ) =-3+3+6=6 So, the constant term is 6 .

$The constant term in the expansion of 3 x + 1 5 x - 1 7 x - 2 2 x - 1 3 x + 2 3 x + 1 x + 2 x + 1 4 x - 1 is$
