Simplify each of the following and express it in the form a + ib :
(8 – 4i) – (- 3 + 5i)

Given: (8 – 4i) – (- 3 + 5i)

Firstly, we open the brackets

8 – 4i + 3 – 5i

= 11 – 9i

Simplify each of the following and express it in the form a + ib :

(–5 + 6i) – (–2 + i)

Simplify each of the following and express it in the form a + ib :

(1 – i)² (1 + i) – (3 – 4i)²

Simplify each of the following and express it in the form a + ib :

Simplify each of the following and express it in the form a + ib :(8 – 4i) – (- 3 + 5i)
