Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:
x=3
x=-4
x=1-2i

Weekly income = 70...she budgets 40 for movies and food.....70 - 40 = 30...that leaves 30 per week that she saves.

24 weeks....saving 30 per week = (24 * 30) = $ 720 <===
