How To Solve Quadratic Equation Graphically. A combination of a linear and a quadratic forms a perfect system of equations or a pair of simultaneous equation. A quadratic equation is always of the form.for example, in the equation we can regard as and g(x) as.solving a quadratic equation means transforming the original equation into a new equation that has the form (where is a constant).
