integral (x³ + 5x² -4)/x² dx =
integral (x³ + 5x²-4)(x^-2)) dx =
integral (x + 5 – 4x^-2)dx =
1/2x² + 5x -4/(-2+1)x^(-2+1) + c =
1/2x² + 5x + x^-1 + c =
1/2x² + 5x + (1/x) + c

integral (2-3x) (2x-3)/ x^5 dx =
integral (4x -6 – 6x² + 9x) /x^5 dx =
integral (-6x² + 13x -6)/x^5 dx =
integral (-6x^-3 + 13x^-4 – 6x^-5) dx =
-6/(-3+1)x^(-3+1) + 13/(-4+1)x^(-4+1) – 6/(-5+1)x^(-5+1) + c =
2x^-2 – (13/3)x^-3 + (3/2)x^-4 + c =
(2/x²) – (13/3x³) + (3/2x^4) + c

integral (2x – 1/x³)²dx =
integral (2x- x^-3) (2x-x^-3) dx =
integral (4x² -2x^-2 -2x^-2 + x^-6) dx =
integr (4x² -4x^-2 + x^-6) dx =
(4/3)x³ – 4/(-2+1)x^(-2+1) + 1/(-6+1)x^(-6+1) + c =
(4/3)x³ + 4x^-1 -(1/5)x^-5 + c =
(4/3)x³ + (4/x) – (1/5x^5) + c
