Let’s call the three third roots of unity 1, α and β. All three of these numbers satisfy the cubic equation x 3 – 1 = 0. In general you have to be careful raising complex numbers to a power, but since ...

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

First, we need to find which number when substituted into the equation will give the answer zero. \(f(1) = {(1)^3} + 4{(1)^2} + (1) - 6 = 0\) Therefore \((x - 1)\)is ...
