Question

(3 + 2x - x²) + (x² + 8x + 5)​

Answer 1

Respuesta:

Hola !

$(3 + 2 \times - \times {}^{2} ) + ( \times {}^{2} + 8 \times + 5)$

$3 + 2 \times - \times {}^{2} + \times {}^{2} - 8 \times + 5$

$(3 + 5) + (2 + 8) \times - ( - 1 + 1) \times {}^{2}$

$8 + (2 - 8) \times + ( - 1 + 1) \times {}^{2}$

$8 + 10 \times + ( - 1 + 1) \times {}^{2}$

$8 + 10 \times + 0$

$8 + 10 \times$

$10 \times + 8$
