Factoring Differences of Squares
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 x - 4
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 Remove the zero pairs. x - 4
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 Remove the zero pairs. x - 4
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 Remove the zero pairs. x - 4
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 Remove the zero pairs. x - 4
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 Remove the zero pairs. x - 4
x2 Model the following problem using algebra tiles: (x + 4)(x – 4) x + 4 Remove the zero pairs. x - 4 What remains is x2 – 16.
Differences of Squares Factor x2 – 64. x2 = x x 64 = 8 8 x2 – 64 = (x + 8)(x – 8)
Differences of Squares Factor 36x2 – 121. 36x2 = 6x 6x 121 = 11 11 36x2 – 121 = (6x + 11)(6x – 11)
Differences of Squares Factor 3x2-48. First, factor out the three. 3(x2-16) Now factor the difference of the squares. 3(x + 4)(x – 4)
