Factoring actually means to "divide out.". When you are asked to "factor" a polynomial expression, you are actually told to write the expression as a product of factors. Often you are asked to factor "relative to the integers." This means that your factors cannot include rational, irrational, or imaginary numbers.
Factoring the trinomial ax^2 + bx + c relative to the integers. Assume a = 1.
Using "educated guessing", find two integers whose product equals c and whose sum equals b. These integers are always factors of c. If this is not possible, the trinomial cannot be factored relative to the integers.
Form a product using two binomials containing the variable x and each of the integers found.
