WebTherefore they have to be of the form 9 1 = 9 or 3 1 = 3. Let f(x) = x3 − 12x + 9. Since f(9) = 630 and f(3) = 0, 3 is a root of f(x). So it can be factored as x3 − 12x + 9 = (x − 3)(ax2 + bx + c) = ax3 + (b − 3a)x2 + (c − 3b)x − 3c Comparing coefficients we get a = 1, b − 3 = 0 b = 3, − 3c = 9 c = − 3. Then x3 − 12x + 9 = (x − 3)(x2 + 3x − 3). WebIf you know the right formulas, you can find or factor the sum or difference of two cubed numbers very easily. All you have to do is identify the cubes, and then substitute them into the appropriate formula.
