x³ - 3x² + 4x - 2
complex roots occur in conjugate pairs
1 + i is a root then so is 1 - i
the factors of the polynomial are therefore
f(x) = (x - 1 )(x - (1 + i))(x - (1 - i))
= (x - 1 )(x² - 2x + 2 ) ( expand factors and simplify )
= x³ - 3x² + 4x - 2

The number of cars, vans and trucks rented are;
Number of Cars = 4 cars
Number of vans = 36 vans
Number of trucks = 108 trucks
<h3>How to solve Algebra Word Problems?</h3>
We are given;
Total number of vehicles = 155 vehicles
Let number of cars be x.
Thus, since Nine times as many cars were rented as vans, we have;
Number of vans rented = 9x
Now, three times as many vans were rented as trucks. Thus;
The number of trucks rented during one month = 3(9x)
Thus;
x + 9x + 27x = 155
37x = 155
x ≈ 4 cars
Number of vans = 9 * 4 = 36 vans
Number of trucks = 3 * 36 = 108 trucks
