+writing this late and cant really remember what we did
+we did some work on completing the square which is never too hard, however i should try and do some more work on it
+try and remember how to put something into a completed square form as well as take it out
+
+x^2 + 6x + 6
+(x + 3)^2 - 3
+method is to half B, then subtract b^2, and add whatever is needed to make sure + c works
+
+this can be used to find the turning point of the graph, the section in brackets needs to have its sign flipped
+this is similar to using factorising to solve a quadratic
+the value outside the bracket stays as is
+in the example given the turning point would be (-3, -3)
