Answer:
5x³ - 2x² + 2x + 9
Step-by-step 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:
Difference of [tex](5x^{3}+4x^{2})-(6x^{2}-2x-9)[/tex] is [tex]5x^{3}-2x^{2}+2x+9[/tex]
Step-by-step explanation:
We need to find the difference of given expression :
[tex](5x^{3}+4x^{2})-(6x^{2}-2x-9)[/tex]
Simplify,
[tex]5x^{3}+4x^{2}-6x^{2}+2x+9[/tex]
combine like terms
[tex]5x^{3}-2x^{2}+2x+9[/tex]
Hence, difference of [tex](5x^{3}+4x^{2})-(6x^{2}-2x-9)[/tex] is [tex]5x^{3}-2x^{2}+2x+9[/tex]
