Factor the Difference of Squares - Set 1

Explanation: The 'difference of squares' indicates the expression is a square minus a square, like x² - 36 which then factors into 2 binomials.  The terms in the binomials are the square monumentalmath of the first term and the square monumentalmath of the second term.  The operations are addition in one binomial and subtraction in the other.  This is indicated by the pattern a² - b² = (a + b)(a - b).  So, x² - 36 will factor into (x + 6)(x - 6).  

Examples: 

x² - 64 = (x + 8)(x - 8)

x² - 100 = (x + 10)(x - 10)

x² - 144 = (x + 12)(x - 12)

Directions: Factor the difference of squares following the pattern of a² - b² = (a + b)(a - b).  Strive to be able to accomplish the problems with ease and then strive to increase your speed.  Good luck and enjoy the challenge!
