Explanation:
Consider the quadratic equation
We want to factorize it and express it in the form
This looks very much like the form
We essentially want to find two numbers that when multiplied give us c (
The factors of 8 are 1, 2, and 4.
note that 2 + 4 = 6 which is the coefficient for x.
Since the numbers 2 and 4 when multiplied equal c and when added equal b they can be used to factorize the expression.
