i)

= ∫(x + 2) dx

= x²/2 + 2x + C

j)

= ∫(x – 1)³ dx

= ∫ (x – 1) (x – 1) (x – 1) dx

= ∫ (x³ – 3x² + 3x – 1) dx

= x⁴/4 – x³ + 3x²/2 – x + C

k)

= ∫(x – 4) (x + 5)dx

= ∫ (x² + x – 20) dx

= x³/3 + x²/2 – 20x + C

l)

= ∫ x (x + 4) (x – 1) dx

= ∫ (x² + 4x) (x – 1) dx

= ∫ (x³ + 3x² – 4x) dx

= x⁴/4 + x³ – 2x² + C
