Answer 1

Hey dear!!

Here's your answer

=====================>>>
$x {3 - 3x {}^{2} }^{} + 3x + 7 \\ = {x}^{3} - 3 \times {x}^{2} \times 1 + 3 \times x \times {1}^{3} - {1}^{2} + 8 \\ = {(x - 1)}^{3} + {2}^{3} \\ = (x - 1 + 2){ | {(x - 1) }^{2} - 2(x - 1) + {(2)}^{2}| } \\ = (x + 1)( {x}^{2} - 2x + 1 - 2x + 2 + 2) \\ = (x + 1)( {x}^{2} - 4x + 5)$
