Answer:
The factored form of a3 + b3 is (a + b)(a2 - ab + b2): (a + b)(a2 - ab + b2) = a3 + a2b - a2b - ab2 + ab2 + b3 = a3 - b3. For example, the factored form of 64x3 + 125 (a = 4x, b = 5) is (4x + 5)(16x2 - 20x + 25). Similarly, the factored form of 343x3 + y3 (a = 7x, b = y) is (7x + y)(49x2 -7xy + y2).
