In this mini-lesson, you'll learn how to work with polynomials using the concept of ratios. We'll see how to factor the numerator and the denominator of a rational expression, cancel out the common factors and reduce the expression into its lowest terms. For example, let's say we have to simplify the expression (9b2
– 11b + 6). To do this, we can factor the numerator 9b2
– 4 to arrive at (3b + 2)(3b – 2), and the denominator 3b2
– 11b + 6 to get (3b – 2)(b – 3). As both the expressions have a common factor, i.e. (3b – 2), it is canceled out, and the remaining simplified expression is (3b + 2)/(b – 3).
