**Answer:**

**m = -4 or m = sqrt(6) or m = -sqrt(6)**

**Step-by-step explanation:**

Solve for m:

m^3 + 4 m^2 - 6 m - 24 = 0

The left hand side factors into a product with two terms:

(m + 4) (m^2 - 6) = 0

Split into two equations:

m + 4 = 0 or m^2 - 6 = 0

Subtract 4 from both sides:

m = -4 or m^2 - 6 = 0

Add 6 to both sides:

m = -4 or m^2 = 6

Take the square root of both sides:

Answer: m = -4 or m = sqrt(6) or m = -sqrt(6)

Fixed Income Mathematics features material and analysis on yield measures for fixed rate bonds and floating rate bonds, key rate duration and yield curve curvature, cash flow characteristics of collateralized debt obligations, and much more.

Fixed income broadly refers to those types of investment security that pay investors fixed interest or dividend payments until its maturity date. At maturity, investors are repaid the principal amount they had invested. Government and corporate bonds are the most common types of fixed-income products.

The **simple interest rate **is 4.7%

<h3>How to determine the

**simple interest rate**?</h3>

The given parameters are:

Principal = $2100

Interest = $1,559.46

Time = 15.8 years

The **simple interest **is calculated as:

I = PRT

Make R the subject

R = I/(PT)

So, we have:

R = 1559.46/(2100 * 15.8)

Evaluate

R = 0.047

Express as percentage

R = 4.7%

Hence, the **simple interest rate **is 4.7%
