Answer 2

Answer:

1. Extracting roots involves isolating the square and then applying the square root property. Remember to include “±” when taking the square root of both sides. After applying the square root property, solve each of the resulting equations.
2. Factoring is a financial transaction and a type of debtor finance in which a business sells its accounts receivable (i.e., invoices) to a third party (called a factor) at a discount. A business will sometimes factor its receivable assets to meet its present and immediate cash needs.
