expand(x+1)(x-(1+ $\sqrt{7}$i)/3)(x-(1- $\sqrt{7}$i)/3)
You asked:
Express \(\left(x + 1\right)\left(x - \frac{1 + \sqrt{7} \cdot i}{3}\right)\left(x - \frac{1 - \sqrt{7} \cdot i}{3}\right)\) in its most expanded form.
MathBot Answer:
\[\left(x + 1\right) \left(x - \frac{1 - \sqrt{7} i}{3}\right) \left(x - \frac{1 + \sqrt{7} i}{3}\right) = x^{3} + \frac{x^{2}}{3} + \frac{2 x}{9} + \frac{8}{9}\]
