Question

Select the correct answer from each drop-down menu. If u = 5 − 2i and v = 2 − 5i, u + v = and u− v = .

Answer 1

Answer:

u+v=7-7i

u-v=3+3i

Step-by-step explanation:

u+v

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

Put like terms together:

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

Simplify:

7+-7i

7-7i

u-v

(5-2i)-(2-5i)

Distribute:

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

Put like terms together:

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

3+3i
