Factorisation by Splitting the Middle Term with Questions

Understanding the Factorization Process

Factorization of quadratic polynomials of the form x2 + bx + c involves a systematic approach to simplify complex expressions into more manageable forms. This method, often referred to as “splitting the middle term,” allows us to break down quadratic equations into factors that are easier to work with.

The Method:

  1. Identify the Numbers: To factorize x2+bx+c, we need to find two numbers, m and n, such that m + n=b and mn=c.
  2. Split the Middle Term: Once we have determined m and n, we split the middle term of the quadratic expression as mx + nx.
  3. Grouping: Next, we group the terms accordingly and factor out common factors.

Example:

Let’s illustrate this process with an example:

Example:    Factorize the following quadratic polynomials:   x2 + 6x + 8
Solution:    In order to factorize x2 + 6x + 8,
we have to find two numbers such that their sum is 6 and the product 8.
Clearly, 6 = 4 + 2 and 4 × 2 = 8
x2 + 6x + 8 = x2 + 4 x + 2x + 8
= (x2 + 4 x) + (2x + 8)
= x(x + 4) + 2 (x + 4) = (x + 2) (x + 4)
