Question

(3x-2)³then find coefficient of x​

Answer 1

$answer \\ (3x - 2)whole \: cube \\ = 27xcube \: - 8 - 54xsquare \: - 36x \\ hence \: the \: coefficient \: of \: x \: is \: - 36$

Answer 2

Answer:

=>(3x-2)³

=>(3x-2)(3x-2)^2

=>3x(3x)^2 + 3x(-2)^2 - 2(3x)^2 - 2(-2)^2

=>3x(9x^2)+ 3x(4) - 2(9x^2) -2(4)

=>27x^3+ 12x-18x^2 -8

=>  therefore the co -efficient of 'x' is 12
