Complete the steps in solving the quadratic function 7x-9=7x^2-49x by completing the square

7x-9=7x^2-49x

-7x              -7x

-9=7x^2-56x

-9=7(x^2-8x+c)-7(c)

c=(-8/2)^2=(-4)^2=16

-9=7(x^2-8x+16)-7(16)

+112                    +112

103=7(x-4)^2

/7     /7

103/7=(x-4)^2

sqrt      sqrt

+/-=x-4

+4              +4

x=+4=3.836+4=7.836

x=4-=4-3.836=0.164

x=7.836, x=0.164

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

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%
