expand [(4-2i)x]2i

Solution

expand

[(4 - 2 i) x] 2 i

Solution

8 i x - 4 i^{2} x

Solution steps

((4 - 2 i) x) \cdot 2 i

Remove parentheses:

(a) = a

= (4 - 2 i) x \cdot 2 i

= 2 i x (4 - 2 i)

Apply the distributive law:

a (b - c) = ab - a c

a = x \cdot 2 i, b = 4, c = 2 i

= x \cdot 2 i \cdot 4 - x \cdot 2 i \cdot 2 i

= 2 \cdot 4 i x - 2 \cdot 2 ii x

Simplify

2 \cdot 4 i x - 2 \cdot 2 ii x : 8 i x - 4 i^{2} x

= 8 i x - 4 i^{2} x
