The LHS will factorise. Then you can equate each factor to zero.
Hi I'm having trouble solving this complex number problem. If anyone can help me out i will really appreciate it. Thanks
here is the question
Use De Moivre's Theorem to solve this equation z^{9} + z^{5} - z^{4} -1 = 0?
I just want to know how can i start solving this??
