Math 110 Guided Lecture Sheet Sect 3.5
1. What is a complex number?
i2 √—1 √—4 √—25
2. Okay, let’s try to factor this, using factor by grouping, and find all the zeros, p(x) = x3 — x2 + 4x — 4.
3. Let’s try another using our methods of rational zeros and synthetic division from last time, p(x) = x3 — 2x + 4.
