Okay, This question would like us complete this square for this quadratic. So completing the square has is turning a X squared plus BX plus C into a Times X plus D squared plus e and D is equal to be over to A and E is equal to C minus. B squared over for a So now we just need to find d and e. So de is equal to be over to a which is negative 2/2 or negative one and then e is equal to C minus. B squared over four A, which is zero minus two squared is four divided by four. So negative one again. So this means that our expression is just X minus one squared minus one because D and E are both just minus one and A is also one, so we have no leading code.
