simplify 3i(2i^2-5i)

Solution

simplify

3 i (2 i^{2} - 5 i)

Solution

15 - 6 i

Solution steps

3 i (2 i^{2} - 5 i)

Apply the distributive law:

a (b - c) = ab - a c

3 i (2 i^{2} - 5 i) = 3 i 2 i^{2} - 3 i 5 i

= 3 i 2 i^{2} - 3 i 5 i

3 i 2 i^{2} = - 6 i

- 3 i 5 i = 15

= - 6 i + 15

Rewrite in standard complex form:

15 - 6 i

= 15 - 6 i
