Proving Polynomial Identities

The following is the difference of cubes identity:

a²-b² = (a + b)(a - b)

• TRUE

• FALSE

The following is the sum of a square identity:

(a + b)² = a² + 2ab + b²

• TRUE

• FALSE

The difference of a square identity tells us that a² - b² =

• a - b

• a + b

• (a+b)(a-b)

The sum of a cubes identity tells us that a³ + b³ =

• a + b
