My apologies, I'm not sure why the copy paste did not take. 

(-4 + x^2 - 3x) + (5x - 3 + x^3) + (-4x + 3 + 6x^3)

(-4 + x^2 - 3x) + (5x - 3 + x^3) + (-4x + 3 + 6x^3)

=-4+x^2-3x+5x-3+x^3-4x+3+6x^3

=7x^3+x^2-2x-4

do i have to solve for x

May 5th, 2015

No, thank you.   May I ask, so I may learn, do exponents remain the same or are they added?

May 5th, 2015

exponents are added when variables are multiplied

but here variables with different exponents are added

so keep as it is.
