Answer:
B
Step-by-step explanation:
a difference of cubes factors in general as
a³ - b³ = (a - b)(a² + ab + b²)
given
p³ - 343q³
= p³ - (7q)³ ← a difference of cubes , then
= (p - 7q)(p² + 7pq + 49q²) ← in factored form
Answer:
x = -4
Step-by-step explanation:
Subtract x^2-16 from both sides:
x^2 +8x +16 = 0
(x +4)^2 = 0 . . factor
x +4 = 0 . . . . . take the square root
x = -4
The one real solution is x = -4.
