Answer:
x = -1 +/-2i
Step-by-step explanation:
Write the equation in standard form to find the roots, also known as the solutions, zeros, or x-intercepts, of the quadratic.
x² + 2x + 5 = 0
Use the quadratic formula by substituting a= 1, b = 2 and c = 5.
Using compound interest and a graphing calculator, it is found that it will take about 15 years for the loan to be paid off.
<h3>What is compound interest?</h3>The amount of money earned, in compound interest, after t years, is given by:
In which:
For this problem, the parameters are given as follows:
A(0) = 95000, r = 0.06, n = 12.
Hence the value of the loan after t years is:
You have monthly payments of $1,200, hence the amount paid after t years is:
P(t) = 12 x 1,200t = 14400t
Then we have to solve for:
A(t) = P(t)
Which is solved in the graph below, meaning that it will take about 15 years for the loan to be paid off.
