Solution. (a)The number is already in the form a + bi a + b i. The complex conjugate is a − bi a − b i, or 2 − i 5-√ 2 − i 5. (b) We can rewrite this number in the form a + bi a + b i as 0 − 1 2i 0 − 1 2 i. The complex conjugate is a − bi a − b i, or 0 + 1 2i 0 + 1 2 i. This can be written simply as 1 2i 1 2 i.

Unit 6: Complex numbers. Humans expand our number system when we find new questions to answer. For finding distances in construction, we opened up to irrational numbers. For solutions for more quadratics, we unveiled complex numbers. The good news is, complex numbers follow most of the same patterns as the numbers that came before.
