You can use the <u>determinant</u><u> (square root)</u> of a quadratic equation to determine the number and type of solutions of the equation.
> 0 → 2 real solutions
- if is a perfect square, then rational sol'ns
- if is not a perfect square, then irrational sol'ns
= 0 → 1 real solution (double root)
< 0 → 2 imaginary(complex) solutions

Answer: the future value is $3788.75
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount invested.
P represents the principal or amount invested.
R represents interest rate
T represents the duration of the investment in years.
From the information given,
P = 3500
R = 5.5
T = 18 months = 18/12 = 1.5 years
I = (3500 × 5.5 × 1.5)/100 = 28875/100
I = 288.75
the future value would be
3500 + 288.75 = $3788.75
