The
Truth vallie of "IF 5+4=9 then 9x3= 12
is​

Answer 1

Answer:

x

4

+9x

3

+35x

2

−x+4

Since x=−5+2i

x

2

=25−4−10i

=21−10i

x

3

=(21−10i)(−5+2i)

=−85+92i

x

4

=441−100−420i

=341−420i

Inserting values we set

=341−420i+9(−85+92i)+35(21−10i)−21+10i+4

=341−765+735−21+4−420i+828i−350i+10i

=294−68i
