I believe the degree of this is 3, assuming that y isn't part of the exponent, and this is a binomial because it has 2 terms.

You need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

8x²<span><span>y has a degree of 3 (x has an exponent of 2, y has 1, and 2+1=3)
</span><span>5xy has a degree of 2 (x has an exponent of 1, </span></span>y has 1, and 1 + 1 = 2)
So, degree = 3       

The polynomial has 2 terms, so it's binomial  ← classification

Select all of the factors of x3 + 5x2 + 2x – 8.
gladu [14]

The factors of this polynomial would be (x + 4)(x + 2)(x - 1).


To find these, you first have to start with long division to find the first factor. If you use x + 4 it would look like this.


\frac{x^{3} + 5x^{2} + 2x - 8}{x + 4} = x^{2} + x - 2


Now we are left with only x^{2} + x - 2. We can factor this by looking for numbers that multiply to the last number and add to the middle number. 2 and -2 multiply to -2 and add to 1. Therefore, we'll use those in parenthesis in their place.


(x + 4)(x + 2)(x - 1)

): If (6x-3)(6x+3)=ax^2-b, what is the value of a? What is the value of b?
lesantik [10]
Answer: a = 36 and b = 9

Explanation:

(6x-3)(6x+3)

= 36x² - 18x - 18x - 9

= 36x² - 9



(6x-3)(6x+3) = ax² - b

36x² - 9 = ax² - b

a = 36 and b = 9

Hope it helps!
