As a graph cuts the axis when the y coordinate is zero, then we substitute \(y = 0\) into the quadratic equation and use algebra to solve. We need to factorise the trinomial. When factorised this ...

The quadratic formula for a quadratic equation in the form of \(ax^2 + bx + c = 0\) is \(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\). The first solution is \(x = \frac ...

As high school students, we follow a rigorous curriculum that teaches themes in Shakespeare, how to dissect a frog or solve a quadratic equation, diligently preparing for the next quiz or exam.
