Answer 2

Answer:

hey mate..... this is your answer

Step-by-step explanation:

Given,

z=(2−3i)

z2−4z+13

=(2−3i)2−4(2−3i)+13

=−5−12i−8+12i+13

=−12i+12i−5−8+13

=0

4z3−3z2+2z+170

=4(2−3i)3−3(2−3i)2+2(2−3i)+170

=4(−46−9i)−3(−5−12i)+2(2−3i)+170

=−184−36i−3(−5−12i)+2(2−3i)+170

=−184−36i+15+36i+4−6i+170

=5−6i
