Answer:
-2b(a) - a^2 -2b^2
Step-by-step explanation:
Just use the 'foil' method, meaning that you multiply the first number of one part (a), to the first and second to the next part (2b, -a)
Then, multiply the second number of that part (-b), to the first and to the next part (2b, -a)
You would get: -2b(a) - a^2 -2b^2
There are 5005 different groups
<h3>How to determine the number of groups?</h3>
The given parameters are:
Players, n = 15
Selected, r = 6
The number of groups is then calculated as:
This gives
Apply the combination formula
Evaluate the expression
Group = 5005
Hence, there are 5005 different groups

Answer:
x²
Step-by-step explanation:
Given: 2x(2x - 3) - 3x(x - 2)
Distributive Property: a(b + c) = ab + ac
1. Distribute
⇒ 2x(2x) + 2x(-3) + -3x(x) + -3x(-2)
⇒ 4x² - 6x - 3x² + 6x
2. Combine like terms
⇒ 4x² - 3x² - 6x + 6x
⇒ x²
