Answer 1

Respuesta:

${8x}^{3} - {36x}^{2} y + 54x {y}^{2} - {27y}^{3}$

Explicación paso a paso:

${(2x)}^{3} - 3 \times {(2x)}^{2} + 3y + 3 \times 2x \times ( {3y)}^{2} - {(3y)}^{2} \\ {8x}^{3} - 3 \times {4x}^{2} \times 3y + 3 \times 2x \times {9y}^{2} - {27y}^{3} = \\ {8x}^{3} - {36x}^{2} y + {54xy}^{2} - {27y}^{3}$
