Answer: x = {1, -1, 2i, -2i}
<u>Step-by-step explanation:</u>
x⁴ + 3x² - 4 = 0
∧
-1 +4 = 3 this works!
(x² - 1)(x² + 4) = 0
x² - 1 = 0 and x² + 4 = 0
x² = 1 and x² = -4
x = ±1 and x = ± 2i
x = 1, -1 and x = 2i, -2i
Answer:
Step-by-step explanation:
Your revenue should be the price demand function * the price:
(x) 350 - 2x =
R(X) = 350x - 
your profit function should be the
Revenue - cost
350x - - 14204 -4x
- + 346x - 14204
b.e.p is where R=0
- + 346x - 14204 =0
Factored: f(x) = -2(x - 106)(x - 67)
bep = 67
9•10^4 / 3•10^3 = 30.
