Distribute $-11i$ through the parentheses
$11i+22{i}^{2}$
By definition ${i}^{2}=-1$
$11i+22 \times \left( -1 \right)$
Any expression multiplied by $-1$ equals its opposite
$11i-22$
Use the commutative property to reorder the terms
$-22+11i$
To find the conjugate of a complex number $a+bi$ , change the sign of the imaginary part
$-22-11i$
