Question

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

Answer 1

`-3x^3+x`

Explanation:

Let's first write the expression:

`-3x+x^3-2x^2-(4x^3-2x^2-4x)`

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.

`-3x+x^3-2x^2-4x^3+2x^2+4x`

Now we combine like terms.

`x-3x^3`

Write the polynomials by decreasing exponents

`-3x^3+x`
