# How do you write (6x^3 − 7x − 4) + (4x^3 + 8x + 3) in standard form?

Aug 2, 2016

$10 {x}^{3} + x - 1$

#### Explanation:

Well, we need to combine like-terms and simpllify the inequality. I do that using the system shown below:

$\textcolor{w h i t e}{. .} 6 {x}^{3} - 7 x - 4$
$+$
$\textcolor{w h i t e}{. .} 4 {x}^{3} + 8 x + 3$
$\textcolor{w h i t e}{}$----------------------------------
$\textcolor{w h i t e}{. .} 10 {x}^{3} + x - 1$

You can do this any way you want, but the key is to combine like terms.
