So far, all the expressions you have applied this method to have had a coefficient of 1 on the x2 term. That is a requirement for completing the square. When faced with an expression that does not meet this requirement, you must factor to make it true before applying this method. One important note is that to move a value outside of a parenthesis, it must be multiplied by the same value multiplying the parenthesis. With this note in mind, use the method of completing the square to solve the quadratic equation -2x2 + 12x = 5.

Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor of ? why or why not? yes, because ab and cd are each the lengths mn and qp. yes, because sides ab and cd are parallel to sides mn and qp. no, because ab is the length mn but cd is the length qp. no, because sides ab and cd have different slopes from sides mn and qp.
