Hello from MrBillDoesMath!
Answer: x^2 - 6.5x + 10.5 = 0
Discussion:
If the roots are 3 and 3.5, then the quadratic equation is
(x -3 ) ( x - 3.5) = 0
or
x * (x - 3.5) - 3 (x - 3.5) = 0
or
X^2 - 3.5X - 3X + 3(3.5) = 0
or
x^2 - 6.5x + 10.5 = 0
Thank you,
MrB

<em>C.) $6,584.91</em>
<em></em>
<em>Step-by-step explanation:</em>
<em />
<em>Amount earned in compound interest = P(1 + r)^n; </em>
<em>where P is the principal, </em>
<em>r is the rate and n is the number of periods.</em>
<em />
<em>
</em>
<em>Amount = 3,000(1 + 14%)^6 = 3,000(1 + 0.14)^6 = 3,000(1.14)^6 = </em><u><em>$6,584.91</em></u>
