Credit: UNSW Sydney A UNSW Sydney mathematician has discovered a new method to tackle algebra's oldest challenge—solving higher polynomial equations. Polynomials are equations involving a variable raised to powers, such as the degree two polynomial: 1 + 4x – 3x2 = 0. The equations are fundamental to math as well as science, where they have broad applications, like helping describe the movement of plane...
