Answer:

Incorrect

Step-by-step explanation:

We are given that

(11+2i)-(3-10i)

We have to find that work shown  in question is correct or not.

(11+2i)-(3-10i)

=11+2i-3+10i  (Using distributive property :[tex]a\cdot (b+c)=a\cdot b+a\cdot c[/tex])

=(11-3)+(2i+10i)

=8+12i

Hence, the work shown is wrong because in step 2 write -10i instead of 10i.
