expand (1-3i)((3-4i)(2,+3i))

expand

(1 - 3 i) ((3 - 4 i) (2, + 3 i))

1 \cdot ((3 - 4 i) (2, + 3 i)) - 3 i ((3 - 4 i) (2, + 3 i))

Solution steps

(1 - 3 i) ((3 - 4 i) (2, + 3 i))

Apply the distributive law:

a (b - c) = ab - a c

a = ((3 - 4 i) (2, + 3 i)), b = 1, c = 3 i

= ((3 - 4 i) (2, + 3 i)) \cdot 1 - ((3 - 4 i) (2, + 3 i)) \cdot 3 i

= 1 \cdot ((3 - 4 i) (2, + 3 i)) - 3 i ((3 - 4 i) (2, + 3 i))

- 2 (11 - 105) + \frac{900 - 76 105}{45}

(1 - tan^{2} (θ)) (sec^{2} (θ))

(cos (v) - 1)^{2}
