Answer 2

Explicação passo-a-passo:

$(2x - 3) - 4(x - 1)(x + 1) + 5 \\ 2x - 3- 4(x - 1)(x + 1) + 5 \\ 2x + 2 - 4(x - 1) \times (x + 1) \\ 2(x + 1 - 2(x - 1) \times (x + 1)) \\ 2(x + 1 - 2( {x}^{2} - 1)) \\ 2(x + 1 - {2x}^{2} + 2) \\ 2(x + 3 - {2x}^{2} ) \\ 2( { - 2x}^{2} + x + 3) \\ 2( { - 2x}^{2} + 3x - 2x + 3) \\ 2( - x \times (2x - 3) - (2x - 3)) \\ 2 \times ( - (2x - 3) \times (x + 1) \\ - 2(2x - 3) \times (x + 1)$
