Question 1033624
(A) {{{int((3x-2)^2, dx) = (1/3)int((3x-2)^2, d(3x-2)) = (1/3)*((3x-2)^3/3) + k = (3x-2)^3/9 +k}}}

(B) {{{int(((x+4)(2x-5))/x^4, dx) = int((2x^2+3x-20)/x^4, dx) = int((2/x^2+3/x^3-20/x^4), dx)  = -2/x-3/(2x^2) +20/(3x^3) + k}}} 

(C)  {{{int(-3/x^3, dx) = -3int(x^(-3), dx) = -3*(x^(-2)/(-2)) + k = 3/(2x^2) + k}}}
