Here is a set of practice problems to accompany the Complex Numbers< section of the Preliminaries chapter of the notes for Paul Dawkins Algebra course at Lamar University. Thus every quadratic polynomial with real coeﬃcients has exactly two solutions, counting multiplicities. To solve the equation \(x^{3} - 1 = 0\), we add 1 to both sides to rewrite the equation in the form \(x^{3} = 1\). 2007 AMC 12A Problems/Problem 18; Intermediate. Complex Numbers D. Jaksch1 Goals: Identify and close gaps in your A-level calculus knowledge. Addition and subtraction of complex numbers has the same geometric interpretation as for vectors. It can often be helpful to use a graphical representation of complex numbers, the so called Argand diagram. "250 Problems in Elementary Number Theory" presents problems and their solutions in five specific areas of this branch of mathe­ matics: divisibility of numbers, relatively prime numbers, arithmetic progressions, prime and composite numbers, and Diophantic equations.
