Answer:
2 + 2i
Step-by-step explanation:
[tex]i-\text{imaginary\ unit}\\\\i=\sqrt{-1}\to i^2=-1\\\\=====================[/tex]
[tex]\dfrac{10-10i}{-5i}=\dfrac{10}{-5i}+\dfrac{-10i}{-5i}=\dfrac{(10)(i)}{(-5i)(i)}+2=\dfrac{10i}{(-5)(i^2)}+2\\\\=\dfrac{10i}{(-5)(-1)}+2=\dfrac{10i}{5}+1=2i+2=2+2i[/tex]
