<h3>How to Subtract Polynomials?</h3>
Given, (10x^4y^2 - 9x^3y - 9y) - (5x^4^y2 + 10x^3y + 12y - 8x), to subtract, open the parentheses using the distributive property.
10x^4y^2 - 9x^3y - 9y - 5x^4^y² - 10x^3y - 12y + 8x
Combine like terms together
10x^4y^2 - 5x^4^y² - 9x^3y - 10x^3y - 9y - 12y + 8x
5x^4^y² - x^3y - 12y + 8x
The highest degree is 4. This determines the degree of a polynomial.
Therefore, the degree of the resulting polynomial, 5x^4^y² - x^3y - 12y + 8x, after subtraction is: degree 4.

Difference-of-Squares Formula:
For a difference of squares a2 – b2, the factorization is:
(a – b)(a + b)
Answer: 31 ft
Step-by-step explanation: Add all of the sides together. So 5 1/3 + 5 1/3 + 10 1/6 + 10 1/6. Convert to the same denominator (6). 5+5+10+10=30. 2/6+2/6+1/6+1/6=1. And 30+1=31
