how to find a factor
"Factors" are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. Some numbers have more than one factorization (more than one way of being factored). For instance, 12 can be factored as 1×12, 2×6, or 3×4.
x²(x + 2) ‐ x(x + 2) ‐ 12(x + 2)
x³+2x² - x²-2x -12x -24
x³- x² + 2x² - 14x -24
