*pupils will probably have no other method available but to solve these
equations using numerical methods<br> (setting up a table or proceeding with guess and
improve). <br>*The pupils might set up tables from the original equations:<br>
x 2 − 7x −6<br>
6 − 12 −6<br>
10 − 12 −6<br>
x x(x − 3) 4x − 6<br>
3 0 4 <br>
*The pupils need to be encouraged to move through the numbers to find the solutions
and to make sense of the solution in the context of the problem.<br>
*It also needs to be made explicit here that we are now dealing with an equation that
involves a term with an unknown of the second degree.
