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
Answer: 1346cm
Step-by-step explanation:
From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.
This simply means that we have to find the perimeter of the rectangular bedspread and this will be:
= 2(length + width)
= 2(435 + 238
= 2(673)
= 1346cm
The length of fridge needed by Reegan is 1346cm.
