WebTo divide complex numbers, we use the following technique (sometimes referred to as “realizing” the denominator): Multiply the numerator and denominator by the complex conjugate of the denominator. Expand the parenthesis in the numerator and denominator. Gather like terms (real and imaginary) remembering that 𝑖 = − 1 . Webx = 3 + i. f ( x) = x 2 − 5 x + 2. x = 10 i. 2 + 10 i 10 i + 3 Substitute 10 i for x. 2 + 10 i 3 + 10 i Rewrite the denominator in standard form. 2 + 10 i 3 + 10 i ⋅ 3 – 10 i 3 – 10 i Prepare to multiply the numerator and denominator by the complex conjugate of the denominator. 6 – 20 i + 30 i – 100 i 2 9 – 30 i + 30 i – 100 i 2 ...
