Question

Evaluate the expression ( - 1 - 6i) - (4 – 3i) and write the result in the form a + bi.The real number a equalsThe real number b equals

Answer 1

`\begin{gathered} -5-3i \\ a=-5;b=-3 \end{gathered}`

Step-by-step explanation

We want to evaluate the expression:

`(-1-6i)-(4-3i)`

To do this, we collect like terms (real part and complex part) and then simplify the expression:

`\begin{gathered} -1-6i-4+3i \\ \Rightarrow-1-4-6i+3i \\ \Rightarrow-5-3i \end{gathered}`

The real number a is -5 and the real number b is -3.
