WebThese complex roots will be expressed in the form a ± bi. A quadratic equation is of the form ax2 + bx + c = 0 where a, b and c are real number values with a not equal to zero. Consider this example: Find the roots: x2 + 4x + 5 = 0. This quadratic equation is not factorable, so we apply the quadratic formula. WebTo determine how many complex roots a polynomial has, we have to use the fundamental theorem of algebra. This theorem tells us that: Fundamental theorem of algebra A … WebIn mathematics and computing, a root-finding algorithm is an algorithm for finding zeros, also called "roots", of continuous functions.
