Factoring Distributive Property

  1. 1. Factoring Undoing Distributive Property Sinnea Douglas
  2. 2. Simple P olynomial Factoring <ul><li>Simple factoring in the context of polynomial expressions is backwards from distributing. That is, instead of multiplying something through a parentheses, you will be seeing what you can take back out and put in front of a parentheses, such as: </li></ul><ul><li>2 x + 6 = 2( x ) + 2(3) = 2( x + 3) </li></ul>
  3. 3. Factor 3 x - 12. <ul><li>The only thing common between the two terms (that is, the only thing that can be divided out front) is a &quot;3&quot;. </li></ul><ul><li>So factor this out front: 3 x - 12 =3( ) </li></ul>
  4. 4. <ul><li>Now, when you divided the &quot;3&quot; out of the &quot;3 x &quot;, this left only the &quot; x &quot; behind, so put that in for the first term inside the parentheses: </li></ul><ul><li>3 x -12 = 3( x ) </li></ul>
  5. 5. <ul><li>When you divided the '3&quot; out of the </li></ul><ul><li>” - 12&quot;, you left a ” - 4&quot; behind, so put that in the parentheses: </li></ul><ul><li>3 x -12 = 3( x - 4) </li></ul><ul><li>This is your final answer: 3( x -4) </li></ul>
