Question

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

Answer 1

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 2

Answer:

Difference of $(5x^{3}+4x^{2})-(6x^{2}-2x-9)$ is $5x^{3}-2x^{2}+2x+9$

Step-by-step 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 $5x^{3}-2x^{2}+2x+9$
