Find the difference of (−5x2 − x3 − 3) − (9x3 + 3x − 6x2). Be sure to show all of your work in a neat and organized fashion.

Use the ^ (shift 6) symbol to show an exponent. For example, x squared can be written as x^2.

$\Large \color{Black}{\Rightarrow -5x^2 - x^3 - 3 - 9x^3 - 3x + 6x^2 }$

I have opened the brackets for you, can you do it now?

gosh you are fast

anonymous · Answer

no not reallyy

parthkohli · Answer

Operate on like terms and you're done

anonymous · Answer

you add/minus terms with the same exponents

parthkohli · Answer

Same exponents and same variables.

anonymous · Answer

for example -x^3 - 9x^3 = -10x^3

parthkohli · Answer

Actually just operate on the numerical coefficients.

$\Large \color{Black}{\Rightarrow 5x^3 + 9x^3 = (5 + 9)x^3 = 14x^3 }$
For example.
