Which expression is the product of (x + 4i)(x − 4i)(x + 4)?
Sophie [7]
Answer= x³+4x²+16x+64

Expand the following:(x + 4 i) (x - 4 i) (x + 4)
(x - 4 i) (x + 4) = (x) (x) + (x) (4) + (-4 i) (x) + (-4 i) (4) = x^2 + 4 x - 4 i x - 16 i = -16 i + (4 - 4 i) x + x^2:
-16 i + (-4 i + 4) x + x^2 (4 i + x)
 | | | | x | + | 4 i
 | | x^2 | + | (4 - 4 i) x | - | 16 i
 | | | | (-16 i) x | + | 64
 | | (4 - 4 i) x^2 | + | (16 + 16 i) x | + | 0
x^3 | + | (4 i) x^2 | + | 0 | + | 0
x^3 | + | 4 x^2 | + | 16 x | + | 64:
Answer: x^3 + 4 x^2 + 16 x + 64

If a=4x and b=3x-3i, when find the value of the a^3b. This is simplifying imaginary number.
Nataly_w [17]

Answer:

192x^4 - 192 x^3i

Step-by-step explanation:

a^3 b

Lets find a^3

a=4x

a^3

(4x)^3

64x^3

b = 3x-3i

a^3b

(64x^3) * (3x-3i)

Distribute

64x^3*3x - 64x^3 *3i

192x^4 - 192 x^3i
