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
I’m just guessing but since 13/4=3.25 that means that the triangle dialated by 3.25 so you multiply 8 by 3.25 and X might be 26
Would it be negative fourty (-40) as the difference between 20 and -10 is 30 so -10 minus 30 is -40 ?
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
Draw a graph of 515 length then then make an angle of 22 width that should get you your answer. Hope this helps!
