Answer 1

Step-by-step explanation:

${x}^{6} \times {7x}^{3} - 8$

$( {x}^{6} {x}^{3} ) \times 7 - 8$

${x}^{6 + 3 } \times 7 - 8$

${x}^{9} \times 7 - 8$

Answer 2

${x}^{6} - 7 {x}^{3} - 8 \\ {x}^{6} + {x}^{3} - 8 {x}^{3} - 8 \\ {x}^{3} ( {x}^{3} + 1) - 8( {x}^{3} + 1) \\ ( {x}^{3} + 1)( {x}^{3} + 8) \\ (x + 1)( {x}^{2} - x + 1)(x + 2)(x - 2x + 4)$
