expand 3i(3-6i)^2

Solution

expand

3 i (3 - 6 i)^{2}

Solution

108 - 81 i

Solution steps

3 i (3 - 6 i)^{2}

Expand

(3 - 6 i)^{2} : - 36 i - 27

= 3 i (- 36 i - 27)

Apply the distributive law:

a (b - c) = ab - a c

3 i (- 36 i - 27) = 3 i (- 36 i) - 3 i 27

= 3 i (- 36 i) - 3 i 27

Simplify

3 i (- 36 i) - 3 i 27 : 108 - 81 i

= 108 - 81 i
