expand (-1+2j)(2,-3)

expand

(- 1 + 2 j) (2, - 3)

- 1 \cdot 2, 1 \cdot 3 + 2 \cdot 2 j, - 2 \cdot 3 j

Solution steps

(- 1 + 2 j) (2, - 3)

= (2, - 3) (- 1 + 2 j)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = - 1, b = 2 j, c = 2,, d = - 3

= (- 1) \cdot 2, (- 1) (- 3) + 2 j \cdot 2, 2 j (- 3)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= - 1 \cdot 2, 1 \cdot 3 + 2 \cdot 2 j, - 2 \cdot 3 j
