Products and Factoring

The ability to factor is also important in finding the solutions of quadratic equations. This will be shown under the subhead "Quadratic Equations."

It will be instructive for you to try to factor the following expressions by transforming each expression into an indicated product:

(a) 3 - 3 + 3 - 4

(b) a2 - a - b

(c) a2 - 2 - a - b + b2

Answers:

(a) 3 - 3 + 3 - 4 = 3 - (3 + 4)

(b) a2 - a - b = a - (a - b)

(c) a2 - 2 - a - b + b2 = (a - b) - (a - b)
