Question

simplify. -(4.7 - 9.3i) + (-9.8i + 4.9) write your answer in the form a + bi.

Explanation:

Step1: Distribute the negative sign

$- (4.7 - 9.3i)=-4.7 + 9.3i$
So the expression becomes $-4.7 + 9.3i-9.8i + 4.9$.

Step2: Combine the real - part terms

Combine $-4.7$ and $4.9$: $-4.7+4.9 = 0.2$

Step3: Combine the imaginary - part terms

Combine $9.3i$ and $-9.8i$: $9.3i-9.8i=-0.5i$

Answer:

$0.2-0.5i$
