How to Factorize a Polynomial Expression?

To factorize is to find two factors that will give equivalent polynomial expression, also, the zeros of the x-values are the solution to the polynomial expression.

Given the equation:

x² + 5x + 6

Break the expression into groups

(x² + 2x) + (3x + 6)

Factor x from (x² + 2x) and 3 from (3x + 6)

x(x + 2) +3(x + 2)

Factor out the common term, (x + 2):

(x + 3)(x + 2)

Solve for x

x + 3 = 0

x = -3

x + 2 = 0

x = -2

Therefore, the factors are: (x + 3)(x + 2)

The solution is: x = -3 or x = -2.
