Question

(4+3i)-(2-i)Simplify, leave in a+bi form

Answer 1

The given expression is

(4 + 3i) - (2 - i)

We would simplify the terms inside the parentheses. The negative sign(- 1) outside the second parentheses would be used to multiply each term inside. We have

4 + 3i + - 1 * 2 + - 1 * - i

4 + 3i - 2 + i

By collecting like terms, we have

4 - 2 + 3i + i

2 + 4i

Thus, the answer in a + bi form is

2 + 4i
