= [(x + 4)(x - 4)] / (x - 4)

When you apply for a loan, the lender will verify your income. They want to be sure you were able to make the payment owed to them.

When you link your loan to an asset, it is called a secured loan. This means that you offer an item of value to the lender just in case you're not able to make your payments.
