Use the difference of two squares to find the product of 22 and 18.

396

Step-by-step explanation:

Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b) (c+d).

Write 22 as (20 + 2) and 18 as (20-2).

(20+2) (20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 396
