Complex Polynomial Identities
... • Complex conjugates are two complex numbers of the form a + bi and a – bi. Both numbers contain an imaginary part, but multiplying them produces a value that is wholly real. Therefore, the complex conjugate of a + bi is a – bi, and vice versa. • The sum of two squares can be rewritten as the produc ...

Multiplication and Division of Whole Numbers
... Notice that both the divisor and the quotient are factors of the dividend. To find the factors of a number, try dividing the number by 1, 2, 3, 4, 5, … Those numbers that divide into the number evenly are its factors. Continue this process until the factors start to repeat. A prime number is a natur ...
