A common expression or idiom
Find a number that evenly divides each term of the expression.
example x5 + 6x4 + 9x3 To factor this expression, see if each "piece" of the expression has a variable in common. In this case, each piece has an X in common. Now we factor out the smallest exponent of X that we see in the expression. x3(x2+6x +9) You could factor the x squared +6x +9 also, into (x + 3)(x+3)
