Ответ:

$1) {(x + 1)}^{3} = (x + 1)( {x}^{2} - x + 1)$

$2){(1 - 2y)}^{3} = (1 - 2y )(1 + 2y + 4 {y}^{2} )$

$3) {(m - n)}^{3} = (m - n)( {m}^{2} + mn + {n}^{2} )$

$4) {(5 + c)}^{3} = (5 + c)(25 - 5c + {c}^{2} )$

$5) {(2 - a)}^{3} = (2 - a)(4 + 2a + {a}^{2} )$

$6) {(x - 4)}^{3} = (x - 4)( {x}^{2} + 4x + 16)$

7)${( {x}^{2} - 1)}^{3} = ( {x}^{2} - 1)( {x}^{4} + {x}^{2} + 1) = (x - 1)(x + 1)( {x}^{4} + {x}^{2} + 1)$

$8) {(x - 2y)}^{3} = (x - 2y)( {x}^{2} + 2xy + 4 {y}^{2} )$

$9) {( {x}^{2} + {y}^{3} )}^{3} = ( {x}^{2} + {y}^{3} )( {x}^{4} - {x}^{2} {y}^{3} + {y}^{6)}$
