Explanation:


in \: our \: case \: we \: find \: \: that \: {x}^(3) + {5x}^(2) - x - 9 \: divided \: by \: x + 2 \: is \: {x}^(2) + 3x - 7 \: with \: reminder \: 5

SO:


{x}^(3) + {5x }^(2) - x - 9 = (x + 2)( {x}^(2) + 3x - 7) + 5

OR


\frac{ {x}^(3) {5x } ^(2) - x - 9 {} }{x + 2} = {x}^(2) + 3x - 7 + (5)/(x + 2)
