Explicación paso a paso:
[tex]4(x + 1) \times 2 - (2x + 5) \times (2x - 1)[/tex]
[tex]8(x + 1) - (2x + 5) \times (2x - 1)[/tex]
[tex]8(x + 1) - (4 {x}^{2} - 2x + 10x - 5)[/tex]
[tex]8x + 8 - (4 {x}^{2} - 2x + 10x - 5)[/tex]
[tex]8x + 8 - (4 {x}^{2} + 8x - 5)[/tex]
[tex]8x + 8 - 4 {x}^{2} - 8x + 5[/tex]
[tex]8 - 4 {x}^{2} + 5[/tex]
[tex]13 - 4 {x}^{2} [/tex]
