$\frac{1}{0.4 - 0.25 i} + 17 + 2 i = ERROR + 2 i$

Explanation

Tap the blue circles to see an explanation.

$\frac{1}{0.4 - 0.25 i} + 17 + 2 i \frac{1}{0.4 - 0 i} + 17 + 2 i \overset{◯}{1} \frac{1}{0} + 2 i \overset{◯}{2} ERROR + 2 i$
①	Add $\frac{1}{00 i}$ and $17$ to get $\frac{1}{0}$ . Step 1: Write $17$ as a fraction by putting $1$ in the denominator. Step 2: To add raitonal expressions, both fractions must have the same denominator. We can create a common denominator by multiplying the second fraction by $0$ . $\frac{1}{00 i} + 17 Step 1 \frac{1}{00 i} + \frac{17}{1} = \frac{1}{00 i} + \frac{17 \cdot 0}{1 \cdot 0} = Step 2 \frac{1}{00 i} + \frac{0}{00 i} = \frac{1}{0}$
②	Cannot divide by zero.
