Factor each
x^3 +2x^2 -4x -8 =0

Standard form:

x3 + 2x2 − 4x − 8 = 0

Factorization:

(x + 2)2(x − 2) = 0

Solutions based on Jenkins–Traub algorithm:

x1 = x2 = −2

x3 = 2

Extrema:

Max1 = (−2, 0)

Min1 = (0.666667, −9.481481)

Step-by-step explanation:

x= -2,2 hope this helps

Step-by-step explanation:

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
