Formula of sum of roots

WebThe formula for the root of linear polynomial such as ax + b is. x = -b/a. The general form of a quadratic polynomial is ax 2 + bx + c and if we equate this expression to zero, we get a quadratic equation, i.e. ax 2 + bx + c = 0. The roots of quadratic equation, whose degree is two, such as ax 2 + bx + c = 0 are evaluated using the formula; WebSep 16, 2024 · There are n distinct nth roots and they can be found as follows:. Express both z and w in polar form z = reiθ, w = seiϕ. Then zn = w becomes: (reiθ)n = rneinθ = seiϕ We need to solve for r and θ. Solve the following two equations: rn = s einθ = eiϕ The solutions to rn = s are given by r = n√s.
