Question

Simplify the expression to a + bi form:(-9 - 8i) -(-4+ 5i)

Answer 1

The expression can be written in the form a+bi as;

`-5-13i`

Step-by-step explanation:

We want to simplify the given expression to the form;

`a+bi`

Given the expression;

`(-9-8i)-(-4+5i)`

solving we have;

`\begin{gathered} (-9-8i)-(-4+5i) \\ =-9-8i-(-4)-(5i)_{} \\ =-9-8i+4-5i \\ =-9+4-8i-5i \\ =-5-13i \end{gathered}`

Therefore, the expression can be written in the form a+bi as;

`-5-13i`

where;

a = -5

b = -13
