Answer:
B)
Step-by-step explanation:
(2x^3+x^2-4x)-(9x^3-3x^2)
2x^3-9x^3+x^2-(-3x^2)-4x
-7x^3+x^2+3x^2-4x
-7x^3+4x^2-4x
Answer:
A. ![12x^{4} -4x^{3} +3x^{2} +3x+20](https://tex.z-dn.net/?f=12x%5E%7B4%7D%20-4x%5E%7B3%7D%20%2B3x%5E%7B2%7D%20%2B3x%2B20)
Step-by-step explanation:
For this problem, we have to combine like terms.
Let's look at the equation:
![(12x^{4} -4x^{3} +7x+6)+(3x^{2} -4x+14)](https://tex.z-dn.net/?f=%2812x%5E%7B4%7D%20-4x%5E%7B3%7D%20%2B7x%2B6%29%2B%283x%5E%7B2%7D%20-4x%2B14%29)
,
,
do not have any other like terms, so we keep all in the final answer.
and
are like terms, so we combine them. ![7x-4x=3x](https://tex.z-dn.net/?f=7x-4x%3D3x)
14 and 6 are like terms, so we combine them. 14+6 = 20
Let's put everything into the final equation:
![12x^{4} -4x^{3} +3x^{2} +3x+20](https://tex.z-dn.net/?f=12x%5E%7B4%7D%20-4x%5E%7B3%7D%20%2B3x%5E%7B2%7D%20%2B3x%2B20)
So, the final answer is A. ![12x^{4} -4x^{3} +3x^{2} +3x+20](https://tex.z-dn.net/?f=12x%5E%7B4%7D%20-4x%5E%7B3%7D%20%2B3x%5E%7B2%7D%20%2B3x%2B20)
