expand (z^3-6z^2+9z-18)+i(-27+12z-3z^2)

expand

(z^{3} - 6 z^{2} + 9 z - 18) + i (- 27 + 12 z - 3 z^{2})

(z^{3} - 6 z^{2} + 9 z - 18) + (- 27 + 12 z - 3 z^{2}) i

Solution steps

(z^{3} - 6 z^{2} + 9 z - 18) + i (- 27 + 12 z - 3 z^{2})

Apply rule:

(a) = a

(z^{3} - 6 z^{2} + 9 z - 18) = z^{3} - 6 z^{2} + 9 z - 18

= z^{3} - 6 z^{2} + 9 z - 18 + i (- 27 + 12 z - 3 z^{2})

Expand

i (- 27 + 12 z - 3 z^{2}) : - 27 i + 12 z i - 3 z^{2} i

= z^{3} - 6 z^{2} + 9 z - 18 - 27 i + 12 z i - 3 z^{2} i

Rewrite in standard complex form:

(z^{3} - 6 z^{2} + 9 z - 18) + (- 27 + 12 z - 3 z^{2}) i

= (z^{3} - 6 z^{2} + 9 z - 18) + (- 27 + 12 z - 3 z^{2}) i

\frac{4 ( 3 - 2 )}{7}

\frac{( x - 5 ) ( x - 10 )}{50}

\frac{1}{3} (3 x - 2)^{4}

\frac{( ( m ^{3} n - 3 x ) 3 )}{( ( n - 2 x ^{5} m ) - 2 )}

(x + 3 (x - 6) = 0) es
