Step 1: Recognize the Quadratic Expression

r r

To factorize a quadratic expression, the first step is to recognize that it is indeed a quadratic expression. For example, consider the expression ay^2 - y - a - 1. Here are the initial algebraic steps:

r r r r Simplify the expression: ay^2 - y^2 - y - a - 1r r r Factor by grouping: ay^2 - y^2 - y - a - 1 y(ay - y) - (a 1)r r r r

Step 2: Look for Common Factors

In some cases, there may be common factors that can be factored out immediately. In the given example, there isn't a straightforward common factor beyond the initial simplification step. However, if the expression were ay^2 - 2ay a, we could factor out an 'a' to get a(y^2 - 2y 1).

Step 3: Use the AC Method

The AC method is a useful technique for factorizing expressions of the form ax^2 bx c. Here's how it works:

r r r r Calculate ac. In the given example, ac (a)(-a - 1) -a^2 - a.r r r Find two numbers that multiply to ac and add to b. In this case, the numbers would be a - 1 and -a, because (a - 1)(-a) -a^2 - a and (a - 1) (-a) -1.r r r Rewrite the middle term using these two numbers: ay^2 - y - a - 1 ay^2 (a - 1)y - (a 1)y - 1r r r Group the terms and factor: y(ay (a - 1)) - 1(ay (a - 1)) (ay (a - 1))(y - 1)r r r r

Step 4: Verify the Factorization

After factorizing, it's always a good idea to verify the result by expanding the factored form to ensure it matches the original expression. This is a crucial step in ensuring the accuracy of your factorization.
