Which of the binomials below is a factor of this trinomial?

x2 + x - 20

a.

x - 4

b.

x + 2

c.

x - 2

d.

x + 4

(x-4) is a factor

Step-by-step explanation:

To factor this trinomial , we find out two factors whose product is -20 and sum is +1

Now we use factors 5 and -4

Take out GCF from each group

Factor out x+5

So (x-4) is a factor

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%
