Factoring Trinomials
Enter the coefficients of the trinomial with their signs (if negative)

(a)x² + (b)x + (c)
The numbers in the two center boxes below are factors of the top box (a)×(c) and when added, equal the bottom box (b).

Value (a)×(c)=
       Value (b)=
Watch the signs when factoring. The factors must result in the labeled terms having the signs shown in their boxes.

   (a)x² +(b1)x  
+(b2)x +(c)
