ANSWER
[tex]-48-25i[/tex]
EXPLANATION
We want to simplify the expression,
[tex](-19+7i) - (29+32i)[/tex]
Let us expand the bracket to obtain,
[tex]-19+7i-29-32i[/tex]
We now group the complex number parts and real number parts.
[tex]-19 -29+7i-32i[/tex]
We simplify further to obtain,
[tex]- 48-25i[/tex]
This is in the form,
[tex]a+bi[/tex]
where
[tex]a=-48[/tex]
and
[tex]b=-25[/tex]
