#### Answer

In order to solve a quadratic equation using the method of completing the square, we first must make the coefficient in front of $x^2$ one if it is not one already. Then, we must make the constant term equal to one half of the coefficient of the x term squared. (For instance, if it was 5x, it would need to be $(5/2)^2 = 25/4$. Then, we create the square and solve. We also use factoring in part a).
