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
310/55 = 5.64 hours
60 minutes per hour
5.64 x 60 = approximately 338 minutes
Im not sure but i think your m is(-2,0) and your b is (6,0)
Hi there!
f(x) = x^3 - 8x^2 + 16x
The multiplicity of a root is the number of times the root appears.
So the answers are
x = 0 and the multiplicity of 1
x = 4 and the multiplicity of 2
I hope this helps!
Good luck!
Answer:
Step-by-step explanation:
Expand:
Subtract 6 from both sides:
Add 4x to both sides:
Divide both sides by 6:
