Factoring Trinomials using SlideDivideIf there is a trinomial that after checking
for GCF still has a number in front of the x2, factor using the slidedivide method.
3x2 2x 5
S Slide
1. Multiply the number in front of the x2 to the product and rewrite your trinomial.
3x2 2x 5

F Factor
2. Factor the trinomial using productsum.
3x2 2x 5
D Divide
3. Divide both numbers in factored form by the number that you slid (# in front of the x2).
3x2 2x 5

S Slide
5. Take the denominator that cannot be reduced and slide it in front of the x in the same
parenthesis.
