WebWhen dividing complex numbers with negative roots, simplify in terms of imaginary numbers and then multiply the numerator and denominator by i. When a binomial is in the denominator, rewrite using i and then multiply the numerator and denominator by the conjugate. dividing by i complex numbers Algebra 2 Roots and Radicals WebMay 24, 2024 · A complex number is in standard form when written as a + bi, where a and b are real numbers. If b = 0, then a + bi becomes a + 0 ⋅ i = a, and is a real number. If b ≠ 0, then a + bi is an imaginary number. If a = 0, then a + bi becomes 0 + bi = bi, and is called a pure imaginary number. We summarize this here.
