1. Match the polynomial identity to the correct answer.
a. Difference of Squares
(a - b)(a2 + ab + b2)
b. Difference of Cubes
a2 + 2ab + b2
c. Square of a Sum
(a + b)(a? - ab + b2)
d. Sum of Cubes
(a - b)(a + b)

Step-by-step explanation:

Given the expressions all that is required is to expand them (using the distributive property) to see which answers they match up to:

For a:

For b:

For c calculate the square of a sum:

(add like terms) c:

For d:

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
