пж помогите срочно!!!​

Answer 1

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

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

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

$4) : {m}^{3} + {n}^{3} = (m + n)( {m}^{2} - mn + {n}^{2} )$

$5) : {p}^{3} + {q}^{3} = (p + q)( {p}^{2} - pq + {q}^{2} )$

$6) : {p}^{3} - {q}^{3} = (p - q)( {p}^{2} + pq + {q}^{2} )$

$7) : {a}^{3} + 8 = (a + 2)( {a}^{2} - 2a + 4)$

$8) : {a}^{3} - 8 = (a - 2)( {a}^{2} + 2a + 4)$

$9) : {m}^{3} + 27 = (m + 3)( {m}^{2} - 3m + 9)$
