Factoring Unit – Day 6 Difference/Sum of Cubes Mrs. Parziale

Do Now Multiply the following using the distributive property: (x – 2)(x 2 + 2x + 4) (2x – 3 )(4x 2 + 6x + 9)

Multiply: (a – b)(a 2 + ab + b 2 ) = The reverse – Factor a 3 – b 3 = Difference of Perfect Cubes

You Try These Factor:

Multiply: (a + b)(a 2 – ab + b 2 ) = The reverse – Factor a 3 + b 3 = Sum of Perfect Cubes

You Try These Factor:

Closure What is the pattern for factoring a difference of cubes? Where is the negative symbol? What is the pattern for factoring a sum of cubes? Where is the negative symbol? Explain how you would factor the following: 27x 6 y =
