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

#10x^3+x-1#

Explanation:

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

#color(white)(..)6x^3-7x-4#
#+#
#color(white)(..)4x^3+8x+3#
#color(white)()#----------------------------------
#color(white)(..)10x^3+x-1#

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