Mr. Coover's class discovered the following pattern. If we multiply three consecutive integers and then add the middle number to the result, the answer is always the middle number cubed. 5 × 6 × 7 + 6 = 216 = 63 10 × 11 × 12 + 11 = 1331 = 113 15 × 16 × 17 + 16 = 4096 = 163 Now, write a third degree polynomial expression in factored form and standard form that represents this pattern. Show that the factored form is equivalent to the expression written in standard form. Substitute three different values for the variable to prove this pattern works for other numbers.

Question

Mr. Coover's class discovered the following pattern.

If we multiply three consecutive integers and then add the middle number to the result, the answer is always the middle number cubed.

5 × 6 × 7 + 6 = 216 = 63

10 × 11 × 12 + 11 = 1331 = 113

15 × 16 × 17 + 16 = 4096 = 163  

 

Now, write a third degree polynomial expression in factored form and standard form that represents this pattern. Show that the factored form is equivalent to the expression written in standard form. Substitute three different values for the variable to prove this pattern works for other numbers.
