Question

4x³-2x²+ 5x - 1 + 8 x + x² - 6x³ + 7 - 6 x + 3 - 3x² - x³ simplify​

Answer 1

Answer:

$= \color{red} \ { - 3 {x}^{3} - 4 {x}^{2} + 7x + 9}$

Step-by-step explanation:

$4 {x}^{3} - 2 {x}^{2} + 5x - 1 +8x + {x}^{2} - 6 {x}^{3} + 7 - 6x + 3 - 3 {x}^{2} - {x}^{3}$

$\underline\color{orange}{Combine \:the \:like\: terms}$

$= 4 {x}^{3} - 6 {x}^{3} - {x}^{3} - 2 {x}^{2} + {x}^{2} - 3 {x}^{2} + 5x + 8x - 6x - 1 + 7 + 3$

$= - 2 {x}^{3} - {x}^{3} - 1 {x}^{2} - 3 {x}^{2} + 13x - 6x + 6 + 3$

$= -3 {x}^{3} - 4 {x}^{2} + 7x + 9$
