expand (1+2i)left(5+3i)left(4+i)

expand

(1 + 2 i) l e f t (5 + 3 i) l e f t (4 + i)

- 17 ee ll ff tt + 51 ee i ll ff tt

Solution steps

(1 + 2 i) l e f t (5 + 3 i) l e f t (4 + i)

= ee (1 + 2 i) (5 + 3 i) (4 + i) ll ff tt

Expand

(1 + 2 i) (5 + 3 i) : - 1 + 13 i

= l e f tl e f t (- 1 + 13 i) (4 + i)

Expand

(- 1 + 13 i) (4 + i) : - 17 + 51 i

= l e f tl e f t (- 17 + 51 i)

Expand

l e f tl e f t (- 17 + 51 i) : - 17 ee ll ff tt + 51 ee i ll ff tt

= - 17 ee ll ff tt + 51 ee i ll ff tt
