Before we look at the new solution, let’s talk about why you want to solve quadratic ... roots as the first one because if you divide both sides by 3, you get the first equation.

If a quadratic equation can be factorised ... The equation factorises to give \((x – 3)(x – 3) = 0\) so there is just one solution to the equation, \( x = 3\). The graph of \(y = x^2 ...
