Solution:
The difference of cubes identity is
if a and b are any two real numbers, then difference of their cubes , when taken individually:
→a³ - b³= (a-b)(a² + a b + b²)→→→Option (D) is true option.
I will show you , how this identity is valid.
Taking R H S
(a-b)(a² +b²+ab)
= a (a² +b²+ab)-b(a² +b²+ab)
= a³ + a b² +a²b -b a² -b³ -ab²
Cancelling like terms , we get
= a³ - b³
= L H S
Is there a list of answers ?
He brought 6 math books and 6 science books
so namely, the "common difference" d = -4, and the first term a₁ = 7.
Answer:
B. f(x) - 2
Step-by-step explanation:
The parent function has a horizontal asymptote at y=0. The graphed function has a horizontal asymptote at y = -2, so the graph has been shifted down 2 units from the graph of the parent function.
Such a vertical shift is accomplished by subtracting 2 from each function value. The graph is of ...
f(x) -2 . . . matches choice B
