Question

F)(2 ×^3 + 5×'2 + 4) + + (2 ×^3 - 3×^2 + x) ​

Answer 1

Resposta:

$4x {}^{3} + 2x {}^{2} + x + 4$

Explicação passo-a-passo:

$f)(2x {}^{3} + 5x {}^{2} + 4) + 2x {}^{3} - 3x {}^{2} + x) =$

$(2 + 2).x {}^{3} ( + 5 - 3).x {}^{2} + x + 4 =$

$4x {}^{3} + 2x {}^{2} + x + 4$

Answer 2

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

$2 {x}^{3} + 5 {x}^{2} + 4 + 2 {x}^{3} - 3 {x}^{2} + x$

$\boxed{4 {x}^{3} + 2 {x}^{2} + x + 4}$
