WebBy Factor theorem, x-k is a factor of the polynomial for each root k. Divide x^{3}-9x^{2}+27x-27 by x-3 to get x^{2}-6x+9. Solve the equation where the result equals to 0. x=\frac{-\left(-6\right)±\sqrt{\left(-6\right)^{2}-4\times 1\times 9}}{2} WebNov 30, 2015 · (x^3+y^3)=(x+y)(x^2-xy+y^2) This is a sum of cubes. This is a semi-important identity to know: (x^3+y^3)=(x+y)(x^2-xy+y^2) Although it doesn't apply directly to this question, it's also important to know that (x^3-y^3)=(x-y)(x^2+xy+y^2). This gives us the rule: (x^3+-y^3)=(x+-y)(x^2∓xy+y^2)
