How do you find the vertex form of a quadratic equation? Algebra Quadratic Equations and Functions Vertex Form of a Quadratic Equation 1 Answer Massimiliano Feb 20, 2015 Since the equation is: #y=x^2+bx+c# the vertex is #V(-b/(2a),-Delta/(4a))#, or, found the #x_v=-b/(2a)# you can substitue it in the equation of the parabola at the place of #x#, finding the #y_v#.
