Complete the square.


Use de Moivre's theorem to compute the square roots of the right side.


Now, taking square roots on both sides, we have


Use de Moivre's theorem again to take square roots on both sides.



![\implies z = {w_2}^{1/2} = \boxed{\pm \sqrt[4]{3} \, \exp\left(-i\dfrac{5\pi}{12}\right)}](https://tex.z-dn.net/?f=%5Cimplies%20z%20%3D%20%7Bw_2%7D%5E%7B1%2F2%7D%20%3D%20%5Cboxed%7B%5Cpm%20%5Csqrt%5B4%5D%7B3%7D%20%5C%2C%20%5Cexp%5Cleft%28-i%5Cdfrac%7B5%5Cpi%7D%7B12%7D%5Cright%29%7D)
 
        
             
        
        
        
X = number of loads
company A : 20x + 8
company B : 24x + 4
20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less
20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A
