Please answer. Find the difference by subtracting the second polynomial from the first. for 10 points!!!!!!!!!!!!!

Answer:
[tex]-3x^3+x[/tex]
Step-by-step explanation:
Let's first write the expression:
[tex]-3x+x^3-2x^2-(4x^3-2x^2-4x)[/tex]
Now we can simplify. Be sure to remember to distribute the "-" to all the numbers in the parentheses. You can picture it like multiply "-1" to all the numbers in the parentheses to make it easier.
[tex]-3x+x^3-2x^2-4x^3+2x^2+4x[/tex]
Now we combine like terms.
[tex]x-3x^3[/tex]
Write the polynomials by decreasing exponents
[tex]-3x^3+x[/tex]
