Identify Factoring Method

Factor this difference of cubes:
x³ - 343

• (x + 7) (x² - 7x + 49)

• (x² + 1) (x - 343)

• (x - 7) (x² + 7x + 49)

• (x² - 343) (x + 1)

Factorize 343x³ - 125y³.

• (7x - 5y)(49x² + 35xy + 25y²)

• (7x - 5y)(49x² + 70xy + 25y²)

• (7x + 5y)(49x² - 35xy + 25y²)

• (7x - 5y)³
