Question

Will give brainlieest. 50 points. (8x + 2x³ - 4x²) - (4 + x³ + 6x)

Answer 1

To simplify the expression (8x + 2x³ - 4x²) - (4 + x³ + 6x), we can combine like terms:

First, distribute the negative sign to the terms within the parentheses:
(8x + 2x³ - 4x²) - (4 + x³ + 6x)
= 8x + 2x³ - 4x² - 4 - x³ - 6x

Next, group the like terms together:
(8x - 6x) + (2x³ - x³) + (-4x²) + (-4)
= 2x + x³ - 4x² - 4

So the simplified form of the expression is 2x + x³ - 4x² - 4.

Answer 2

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

Explanation:

(8x + 2
`x^(3)` - 4
`x^(2)`) - (4 +
`x^(3)` + 6x)

= 8x + 2
`x^(3)` - 4
`x^(2)` - 4 -
`x^(3)` - 6x

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

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