3+289-\left(5-i\right)z+2\times \left(2i\right)=0
Calculate 17 to the power of 2 and get 289.
292-\left(5-i\right)z+2\times \left(2i\right)=0
Add 3 and 289 to get 292.
292-\left(5-i\right)z+4i=0
Multiply 2 and 2i to get 4i.
292-\left(5-i\right)z=-4i
Subtract 4i from both sides. Anything subtracted from zero gives its negation.
292+\left(-5+i\right)z=-4i
Multiply -1 and 5-i to get -5+i.
\left(-5+i\right)z=-4i-292
Subtract 292 from both sides.
\left(-5+i\right)z=-292-4i
The equation is in standard form.
\frac{\left(-5+i\right)z}{-5+i}=\frac{-292-4i}{-5+i}
Divide both sides by -5+i.
z=\frac{-292-4i}{-5+i}
Dividing by -5+i undoes the multiplication by -5+i.
z=56+12i
Divide -292-4i by -5+i.
