Answer:
3(a - b)(a + b)
Step-by-step explanation:
Factorize: (2a - b)² - (a - 2b)²
- Different of Perfect a Square rule: a² - b² = (a + b)(a - b)
(2a - b)² - (a - 2b)² = [(2a - b) + (a - 2b)] × [(2a - b) - (a - 2b)]
1. Distribute and Simplify:
Distribute the (+) sign on the first bracket and simplify: [(2a - b) + (a - 2b)] → 2a - b + a - 2b → (3a - 3b)
Distribute the (-) sign on the first bracket and simplify: [(2a - b) - (a - 2b)] → 2a - b – a + 2b → (a + b)
We now have:
(3a - 3b)(a + b)
2. Factor out the Greatest Common Factor (3) from 3a - 3b:
(3a - 3b) → 3(a - b)
3. Add "(a + b)" back into your factored expression:
3(a - b)(a + b)
Hope this helps!
Answer:
y=5
Step-by-step explanation:
y= 5 is always parallel to x axis
If f(x) is the inverse of g(x) then if f(a)=b then g(b)=a
so if G(s) is the inverse of S(g) then if G(2)=16 then S(16)=2, true
yes, it's true
A is answer
Answer: y= -x +4
negative slope because our graph goes down as we go right.
+4 indicating how high on our y axis we go up/down
He spent exactly 20.25, so it's A.
