For a quadratic equation of the form \(y = k{(x - a)^2} + b\), the following diagram shows the main properties: If k > 0, the vertex is a minimum turning point If k < 0, the vertex is a maximum ...

Then those would be the roots of quadratic. Multiplying out the right hand side gives This is true when -B=R+S and when C=RS ... approach proves that quadratic equations have two roots.
