Factorisation by Splitting the Middle Term With Questions

Factorization of Quadratic polynomials of the form x2 + bx + c.
(i) In order to factorize x2 + bx + c we have to find numbers m and n such that m + n = b and mn = c.
(ii) After finding m and n, we split the middle term in the quadratic as mx + nx and get desired factors by grouping the terms.

Let us understand by 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)
