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

$-22-11i$
