1 writing this late and cant really remember what we did 2 we did some work on completing the square which is never too hard, however i should try and do some more work on it 3 try and remember how to put something into a completed square form as well as take it out 4 5 x^2 + 6x + 6 6 (x + 3)^2 - 3 7 method is to half B, then subtract b^2, and add whatever is needed to make sure + c works 8 9 this can be used to find the turning point of the graph, the section in brackets needs to have its sign flipped 10 this is similar to using factorising to solve a quadratic 11 the value outside the bracket stays as is 12 in the example given the turning point would be (-3, -3)
