expand

- 9 (5 + 3 h - 4 i)

(- 45 - 27 h) + 36 i

Solution steps

- 9 (5 + 3 h - 4 i)

Apply the distributive law:

m (a + b + c) = ma + mb + m c

- 9 (5 + 3 h - 4 i) = - 9 \cdot 5 - 9 \cdot 3 h - 9 (- 4 i)

= - 9 \cdot 5 - 9 \cdot 3 h - 9 (- 4 i)

Simplify

- 9 \cdot 5 - 9 \cdot 3 h - 9 (- 4 i) : - 45 - 27 h + 36 i

= - 45 - 27 h + 36 i

Rewrite in standard complex form:

(- 45 - 27 h) + 36 i

= (- 45 - 27 h) + 36 i
