Factor completely x8 − 16.

A: (x4 − 4)(x4 + 4)
B: (x2 − 2)(x2 + 2)(x4 + 4)
C: (x2 − 2)(x2 + 2)(x4 − 4)
D: (x2 − 2)(x2 − 2)(x4 − 4)

B

Step-by-step explanation:

Hence, option B is the correct answer.

B

Step-by-step explanation:

x^8 - 16

(x^4)^2 - 4^2

(x^4 + 4) (x^4 - 4)

(x^4 + 4) ((x^2)^2 - 2^2)

(x^4 + 4) ((x^2 + 2) x^2 - 2))

(x^4 + 4) (x^2 + 2) (x^2 - 2)

Rearrange based on choices

(x^2 - 2) (x^2 + 2) (x^4 + 4)

im alright what do you need

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
