Question

(7x 3 + 8x 2 – 2x -10) + (4x 3 – 4x 2 + 10x + 8)

Answer 1

Respuesta:

(13x - 5)+(10x +14) = 23x + 11

Answer 2

Respuesta:

$(7x \times 3 + 8x \times 2 - 2x - 10) + (4x \times 3 - 4x \times 2 + 10x + 8)$

$(21x + 16x - 2x - 10) + (12x - 8x + 10x + 8)$

$(35x - 10) + (14x + 8)$

$35x - 10 + 14x + 8$

$= 49 x - 2$
