Manipulating algebraic expressions is an import concept found throughout the GMAT exam - not only in the Algebraic sections but in solving geometric problems as well. Below are several factoring formulas that will be helpful.

a² - b²	=	(a + b)(a - b)
a² + 2ab + b²	=	(a + b)(a + b)
a² - 2ab + b²	=	(a - b)(a - b)
a³ + b³	=	(a + b)(a² - ab + b²)
a³ - b³	=	(a - b)(a² + ab + b²)
a³ + 3a²b + 3ab² + b³	=	(a + b)³
a³ - 3a²b + 3ab² - b³	=	(a - b)³
