Answer 1

Respuesta:

$(x - 1)(x + 1) \\ {x}^{2} + x - x - 1 \\ {x}^{2} - 1$

${(3x + 5)}^{2} \\ (3x + 5)(3x + 5) \\ 9 {x}^{2} + 15x + 15x + 25 \\ 9 {x}^{2} + 30x + 25$

$(2x - 14)(2x + 14) \\ 4 {x}^{2} + 28x - 28x - 196 \\ 4 {x}^{2} - 196$

$(12x - 3)(12x - 3) \\ 144 {x}^{2} - 36x - 36x + 9 \\ 144 {x}^{2} - 72x + 9$

$(x - 6)(x + 10) \\ {x}^{2} + 10x - 6x - 60 \\ {x}^{2} + 4x - 60$

$(4x - 8)(4x + 3) \\ 16 {x}^{2} + 12x - 32x - 24 \\ 16 {x}^{2} - 20x - 24$

${(5x - 4)}^{3} \\ (5x - 4)(5x - 4)(5x - 4) \\ (25 {x}^{2} - 20x - 20x + 16)(5x - 4) \\ (25 {x}^{2} - 40x + 16)(5x - 4) \\ 125 {x}^{3} - 100 {x}^{2} - 200 {x}^{2} + 160x + 80x + 64 \\ 125 {x}^{3} - 300 {x}^{2} 240x + 64$

${(12 + 8x)}^{3} \\ (12 + 8x)(12 + 8x)(12 + 8x) \\ (144 + 96x + 96x + 64 {x}^{2} )(12 + 8x) \\ (144 + 192 + 64 {x}^{2} )(12 + 8x) \\ 1728 + 1152x + 2304 + 1536x + 768 {x}^{2} + 512 {x}^{3} \\ 4032 + 2688x + 768 {x}^{2} + 512 {x}^{3}$
