Using the points where the graph touches the x axis, you can write the equation y=(x+1)(x-2)^2. This shows the solutions for where the graph meets the x axis where the squared shows a repeated root. Basically just working backwards from how you would normally draw a graph. Multiply this out to get your answer in the form required
