Hi, first steps can be: Spoiler: Spoiler: Spoiler:
Factoring by Grouping MAY work: x^3 - 3x^2 - x^2 + x^2 + 3x - 4x + 4x - 28 = (x^3 - 3x^2 - x^2) + (x^2 - 4x) + (3x + 4x - 28) = (x^3 - 4x^2) + (x^2 - 4x) + (7x - 28) = x^2(x - 4) + x(x - 4) + 7(x - 4) = Well, i think you can finish this easily, . . . .
