Jawab:
¹/₄(x²-x+3)⁴ + C [C]

Penjelasan dengan langkah-langkah:
∫(2x-1)(x²-x+3)³ dx =
u = x²-x+3
du = (x²-x+3)'dx
du = (2x²⁻¹-1x¹⁻¹+0) dx
du = 2x-1 dx
dx = (1/(2x-1))du
∫(2x-1)(x²-x+3dx =
∫(2x-1)(u(1/(2x-1))du =
∫(2x-1)/(2x-1) u³ du =
∫u³du
¹/₃₊₁u³⁺¹ + C =
¹/₄u⁴ + C =
u = x²-x+3, maka
¹/₄(x²-x+3)⁴ + C [C]
