4(x+1)2-(2x+5)(2x-1)

Answer 1

Explicación paso a paso:

$4(x + 1) \times 2 - (2x + 5) \times (2x - 1)$

$8(x + 1) - (2x + 5) \times (2x - 1)$

$8(x + 1) - (4 {x}^{2} - 2x + 10x - 5)$

$8x + 8 - (4 {x}^{2} - 2x + 10x - 5)$

$8x + 8 - (4 {x}^{2} + 8x - 5)$

$8x + 8 - 4 {x}^{2} - 8x + 5$

$8 - 4 {x}^{2} + 5$

$13 - 4 {x}^{2}$
