I am taking a consumer math class to sharpen my financial skills in making educated decisions.
<h3>What is consumer math?</h3>
Consumer math is mathematics that uses basic math skills in real-life everyday situations.
Some real-life situations requiring consumer math abilities include shopping, calculating taxes, estimating the monthly budget, and calculating the interest rate for a loan.
Students taking consumer math classes can balance a checkbook, create a budget, buy a car or home, keep personal financial records, and pay taxes.
Thus, this consumer math course will enable me to make educated personal finance decisions.

<h3>How to simplify a fractional expression?</h3>
The steps to simplify a fractional expression are:
- Factorize the expressions both in the numerator and the denominator using different methods
- Remove the common terms in the numerator and denominator
- Thus, the simplified expression will be obtained.
<h3>Calculation:</h3>
The given expression is
Factorizing the numerator:
x² - 4x - 21 = x² - 7x + 3x - 21
= x(x - 7) + 3(x - 7)
= (x - 7)(x + 3)
Then,
= 
common factor (x + 3) is canceled out from both the numerator and the denominator
So,
=
Therefore, the simplified expression is .
