.

$1. {(a + b)}^{2} = {a}^{2} + {b}^{2} + 2ab \\ 2. {(a - b)}^{2} = {a}^{2} + {b}^{2} - 2ab \\ 3. {a}^{2} - {b}^{2} = (a + b)(a - b) \\ 4.(x + a)(x + b) = {x}^{2} + (a + b)x + ab \\ 5. {(a + b + c)}^{2} = {a}^{2} + {b}^{2} + {c}^{2} + 2ab + 2bc + 2ac \\ 6. {(a + b)}^{3} = {a}^{3} + {b}^{3} + 3ab(a + b) \\ 7. {(a - b)}^{3} = {a}^{3} - {b}^{3} - 3ab(a - b) \\ 8. {a}^{3} + {b}^{3} + {c}^{3} - 3abc = (a + b + c)( {a}^{2} + {b}^{2} + {c}^{2} - ab - bc - ac) \\ 9. {a}^{3} + {b}^{3} = (a + b)( {a}^{2} - ab + {b}^{2} ) \\ 10. {a}^{3} - {b}^{3} = (a - b)( {a}^{2} + ab + {b}^{2} )$
