Transcribed Image Text:Find all the roots of
f (z) = (-5+ j4) z² + (3 – j5) z + 4 + j3
For all computed DECIMAL values that are NOT the final answer, round off decimal
values to 4 decimal places.
Then, round off the final answer to 2 decimal places.
For this question, whenever permitted by the calculation, such as rectangular to polar
conversion or operations of complex numbers, it is recommended you use a calculator.
But, as discussed in class, you cannot use a calculator to compute directly the square
root of a complex number since it will display an error.
