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 crosses the \({x}\)-axis twice, once at \({x}\) = -7 and once at \({x}\) ...

Sometimes we have to form quadratic equations to help us solve problems. Dave has a box which has one side of length (\({x}\) – 3) and another side of length (\({x}\) + 2). Find an expression fo ...
