FOIL method | 1. write the products of the terms 2. multiply 3. combine like terms |
difference of squares | two perfect sqaures seperated by a subtraction sign |
square of a difference | if a and b are any numbers, (a-b)**2 = (a-b)(a-b) = a**2-2ab+b**2 |
square of a sum | if a and b are any numbers, (a+b)2 = (a+b)(a+b) = a**2+2ab=b**2 |
