Answer:
C
Step-by-step explanation:
The expression given is a difference of cubes and factors as
a³ - b³ = (a - b)(a² + ab + b²)
8 = (2
 = (2 )³ ⇒ a = 2
)³ ⇒ a = 2
27 = (3y²)³ ⇒ b = 3y²
 = (3y²)³ ⇒ b = 3y²
Hence 2 factors are
(2 - 3y²) and
 - 3y²) and
((2 )² + (2
)² + (2 × 3y²) + (3y²)²)
 × 3y²) + (3y²)²)
= (4 + 6
 + 6 y² + 9
y² + 9 )
)
Hence the factored form of the expression is C

Answer:

Step-by-step explanation:
The given quadratic equation is:

Comparing it with the standard form of Quadratic Equation  , we get:
 , we get:
 a = 3, b = -9 and c = 1
Discriminant = b² - 4ac
D = (-9)²-4(3)(1)
D = 81 - 12
D = 69
