So the solutions of the equation are \({x}\) = -2 and \({x}\) = -7. Where the graph crosses the line \({y}\) = 0 we will have our solutions. As the graph is quadratic we can see that the line ...

An animated guide to factorising quadratic expressions and equations. Examples are used to show how to find factors that multiply to give the number term and add to give the x coefficient in an ...
