Choose the option that gives an expression for the indefinite integral

ʃ (cos(4x) + 2x^2)(sin(4x) − x) dx.

In each option, c is an arbitrary constant.

Options

A cos(4x) + 2x^2 +c

B -1/8cos(4x) + 2x^2)^2 +c

C 1/4 (sin(4x) − x)^2 + c

D (1/(2 (sin(4x) − x)) +c

E ln cos(4x) + 2x^2 +c

F ln (sin(4x) − x) + c

G ln (cos(4x) + 2x^2)/(sin(4x) – x)+ c

H ln (2x^2 sin(4x) − x cos(4x))+ c
