Answer 1

1. (-3+i)+(4+6i)=1+7i so the answer is  c

2. (-4-6i)+(-2-3i)=-6-9i so the answer is d

3. (4+i)-(-3+2i)=7-i so the answer is a

4. (-2+5i)+(-4-2i)=-6+3i so the answer is d

5. (4+2i) (3-i) =no answer

6. (-3+i)(2+7i) =no answer

7. (5+2i)(5-2i)=no answer



i think number 5 up to 7 it gone quadratic equation  

Answer 2

(-3+i) + (4+6i) =

1 + 7i = c

(-4 - 6i) + (-2 - 3i) =

-6 - 9i = d

(4 + i) - (-3 + 2i) =

7 - 1i = a

(-2 + 5i) + (-4 - 2i) =

-6 + 3i = d

(4 + 2i)(3 - i) =

12 -4i + 6i -2i^2 = 12 + 2i - 2(-1) = 12 + 2 + 2i = 14 + 2i = a

(-3 + i)(2 + 7i) =

-6 - 21i + 2i + 7i^2 = -6 -19i -7 = -13 -19i = c

(5 + 2i)(5 - 2i) =

25 - 10i + 10i - 4i^2 = 25 + 4 = 29 = d
