Quadratics Box Method

Identify the error:

• found the wrong factors of ac (-18)

• factors did not add to b (7)

• first term and last term entered incorrectly in the box

• Factored out the GCF in each column and row incorrectly

(e +2)(e + 3)

• e² + 5e + 6

• e² + e + 6

• e² + 5e + 5

• e² + 6e + 6

To finish factoring a quadratic, Jose began to take the GCF of every row and column. Identify what term would fill each space. Space A: ​ (a)   ​ Space B:​ (b)   ​ Space C: ​ ​ (c)   ​ Space D:​ (d)   ​
