Practice problem
Simplify: a−ba+bi\frac{a-b}{a+bi}a+bia−b
(a−b)(a+bi)a−bi\frac{(a-b)(a+bi)}{a-bi}a−bi(a−b)(a+bi)
(a−b)(a−bi)(a+bi)\frac{(a-b)(a-bi)}{(a+bi)}(a+bi)(a−b)(a−bi)
(a−b)(a−bi)a2+b2\frac{(a-b)(a-bi)}{a^2+b^2}a2+b2(a−b)(a−bi)
(a−b)(a+bi)a2+b2\frac{(a-b)(a+bi)}{a^2+b^2}a2+b2(a−b)(a+bi)
Type a concept, like “slope” or “photosynthesis”.
