6.)
(3+7i) - (2+5i)
= 3 + 7i - 2 - 5i
= (3-2) + (7-5)i

12.)
(3i)(5i)
= 3i*5i
= 15*i^2
= 15*(-1) [Because, i^2 = -1]

16.)
(2-i)(-5+6i)
= 2*(-5) + 2*6i - i*(-5) - i*6i
= -10 + 12i + 5i - 6i^2
= -10 + 17i - 6*(-1) [Because, i^2 = -1]
= -10 + 17i + 6

20.)
(3+8i)(3-8i)
= 3^2 - (8i)^2
[Because, (a+b)(a-b) = a^2 - b^2]
= 9 - 64*i^2
= 9 - 64*(-1)
= 9 + 64

24.)
(3-5i)/(2-i)
Multiply in numerator and denominator by the conjugate of denominator
=[(3-5i)*(2+i)]/[(2-i)*(2+i)]
= [ 3*2 + 3*i - 5i*2 - 5i*i]/(2^2 - i^2)
= [6 + 3i - 10i - 5*i^2]/(4 - (-1)) [Because, i^2 = -1]
= [6 -7i -5*(-1)]/(4+1)
= [6 -7i + 5]/5

26.)
(-5+10i)/(3+4i)
Multiply in numerator and denominator by the conjugate of denominator
=[(-5+10i)*(3-4i)]/[(3+4i)*(3-4i)]
= [-5*3 - 5*(-4i) + 10i*3 + 10i*(-4i)]/(3^2 - (4i)^2)
= [ -15 + 20i + 30i - 40*i^2]/(9 - 16*i^2)
= [ -15 + 50i - 40*(-1)]/(9 - 16*(-1))
= [-15 + 50i + 40]/(9+16)
= (25 + ...

• " In question 2, you incorrectly add in the \$3.00 dividend that was just paid to determine the value of the stock price using the dividend discount model. In question 4 response, it should have also been recognized that dividend discount models are not useful if any of the parameters used in the model are inaccurate. "
