Question

S = (x + 6)² - (x + 8)(x + 4) + 1.​

Answer 1

Explicación paso a paso:

$s = ( {x + 6)}^{2} - (x + 8)(x + 4) + 1 \\ s = {x}^{2} + 12x + 36 - ( {x}^{2} + 4x + 8x + 32) + 1 \\ {x}^{2} + 12x + 36 - ( {x}^{2} + 12x + 32) + 1 \\ {x}^{2} + 12x + 36 - {x}^{2} - 12x - 32 + 1 \\ 36 - 32 + 1 \\ 5$
