for class 7​

Answer 1

Simply multiply it by -1

Simply multiply it by -1So the additive inverse of any complex number a+ib is -1* (a+ib) which is -a-ib

Simply multiply it by -1So the additive inverse of any complex number a+ib is -1* (a+ib) which is -a-ibe.g. Additive inverse of 3+4i will be -3-4i
