Question

factorise the following sum given below:-

Answer 1

Factoring a3 - b. For example, the factored form of 27x3 - 8 (a = 3x, b = 2) is (3x - 2)(9x2 + 6x + 4). Similarly, the factored form of 125x3 -27y3 (a = 5x, b = 3y) is (5x - 3y)(25x2 +15xy + 9y2). To factor a difference of cubes, find a and b and plug them into (a - b)(a2 + ab + b2).
