Question

Evaluate the expression ( - 4 - 3i) + (- 1+ 3i) and write the result in the form a + bi.The real number a equalsThe real number b equals

Answer 1

• The real number a = -5

,

• The real number b = 0

Step-by-step explanation:

Given the expression:

`\mleft(-4-3i\mright)+(-1+3i)`

First, remove the brackets:

`=-4-3i-1+3i`

Next, bring the like terms together:

`\begin{gathered} =-4-1-3i+3i \\ =-5+0i \end{gathered}`

The result in the form a+bi is:

`-5+0i`

Thus:

• The real number a = -5

,

• The real number b = 0
