[tex](2 {x}^{2} + x + 1) \: {x}^{ - 3} \: dx[/tex] Yang bisa minta bantuannya, Dong. Sama caranya juga. #Kalkulus

[tex]integral \: (2 {x}^{2} + x + 1) {x}^{ - 3} dx \\ integral( {2x}^{ - 1} + {x}^{ - 2} + {x}^{ - 3} ) dx \\ integral( \frac{2}{x} + {x}^{ - 2} + {x}^{ - 3} )dx \\ = 2 ln |x| + \frac{ {x}^{ - 1} }{ - 1} + \frac{ {x}^{ - 2} }{ - 2} + c \\ = ln {x}^{2} - \frac{1}{x} - \frac{1}{2 {x}^{2} } + c[/tex]
