Answer 1

Explicação passo-a-passo:

$(7x^3+12x^2-4x+3)+(-5x^3+6x^2+7x-4)$

$=7x^3+12x^2-4x+3-5x^3+6x^2+7x-4$

$=7x^3-5x^3+12x^2+6x^2-4x+7x+3-4$

$=2x^3+18x^2+3x-1$

Answer 2

Oie, Td Bom?!

$(7x {}^{3} + 12x {}^{2} - 4x + 3) + ( - 5x {}^{3} + 6x {}^{2} + 7x - 4)$

$7x {}^{3} + 12x {}^{2} - 4x + 3 - 5x {}^{3} + 6x {}^{2} + 7x - 4$

$2x {}^{3} + 18x {}^{2} + 3x - 1$
