Question

What is the difference of the polynomials? (5x3 + 4x2) – (6x2 – 2x – 9)

Answer 1

5x³ - 2x² + 2x + 9

Explanation:

distribute both parenthesis, noting the second one is distributed by - 1

= 5x³ + 4x² - 6x² + 2x + 9 ( collect like terms )

= 5x³ - 2x² + 2x + 9

Answer 2

Difference of
`(5x^(3)+4x^(2))-(6x^(2)-2x-9)` is
`5x^(3)-2x^(2)+2x+9`

Explanation:

We need to find the difference of given expression :

`(5x^(3)+4x^(2))-(6x^(2)-2x-9)`

Simplify,

`5x^(3)+4x^(2)-6x^(2)+2x+9`

combine like terms

`5x^(3)-2x^(2)+2x+9`

Hence, difference of
`(5x^(3)+4x^(2))-(6x^(2)-2x-9)` is
`5x^(3)-2x^(2)+2x+9`
