Respuesta:
[tex]\mathrm{(1+2i)+(-3+4i)i-(2-2i)(1-2)}[/tex]
[tex]\mathrm{1+2i+\left(-3+4i\right)i-\left(2-2i\right)\left(1-2\right)}[/tex]
[tex]\mathrm{1+2i+\left(-4-3i\right)-\left(-\left(2-2i\right)\right)}[/tex]
Eliminamos paréntesis y agrupamos términos
[tex]\mathrm{1+2i-4-3i+2-2i}[/tex]
[tex]\mathrm{2i-3i-2i+1-4+2}[/tex]
[tex]\mathrm{2i-3i-2i=-3i}[/tex]
[tex]\mathrm{1-4+2=-1}[/tex]
Solución:
[tex]\boxed{\mathrm{-1-3i}}[/tex]
