Answer:

8x^6-10x^5+4x^4-5x^3-4x+5

Step-by-step explanation:

Lest distribute the expression given

this is multiply the first term (4x) with the longer expression (2x^5+x^3-1) and then, multiply the second term (-5) with the longer expression (2x^5+x^3-1).

When the above is finish, simply sum all together.

4x* (2x^5+x^3-1)= 8x^6 +4x^4-4x

-5*(2x^5+x^3-1)=-10x^5-5x^3+5

The sum of all together (respecting the coefficient they belong) is shown:

8x^6-10x^5+4x^4-5x^3-4x+5

when you multiply a difference of two squares, why is your answer a binomial instead of a trinomial like when you multiply the s

aleksley [76]

Difference of two squares:

(a+b)(a-b) = a² - b²
(a-b)(a+b) = a² - b²

The difference of two squares results to a binomial because the middle term cancels each other out.

example:
a = 2 ; b = 3

(2 - 3)(2 + 3) = 2(2+3)-3(2+3) = 4+6-6+9 = 4 + 0 + 9 = 4 + 9
