Answer:

Step-by-step explanation:
Take one polynomial from the other means to perform the sub.traction of them. Recall that it is better to use grouping symbols when subtracting polynomials, so we get the signs right when combining like terms:
The indicated subtraction is: 
Make sure that before removing the grouping symbol (parenthesis) that is preceded by a negative sign, we change the signs of every term inside it. Then combine like terms to get the final answer:

Which is the last option shown in the question
Step-by-step explanation:
81x⁴ - 16y⁴
(9x²)² - (4y²)²
(9x² + 4y²)(9x² - 4y²)
(9x² + 4y²)(3x + 2y)(3x - 2y)
Answer: The answer is 22,452
Step-by-step explanation: Multiply 6×2 which will be 12
Put the 1 from the 12 on top of the 4 then do 4×6+1 it will equal 25
Then put the 2 on top of the 7 then do 7×6+2 it will equal 44
Then put the 4 on top of the 3 then do 3×6+4 it will equal 22
And that's how you get your answer.
