The equation has three integer solutions. Two of these solutions are and .

Work out the third solution to the equation.

x = - 2

Step-by-step explanation:

x³-x²+ax+b = (x-1)(x-2)(x+c) = x³ + (c-3)x² + (2-3c)x +2c

c-3 = -1       C = 2

a = 2 - 3c = 2 - 3*2 = - 4

b = 2c = 4

third solution: x+2=0    x=-2

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%
