The answer to this question is choice B. To complete the square, we take the coefficient on the x term, halve it, and then square it. This results in -9/2, and then 81/4. This value of 81/4 is added to both sides, allowing for factorization of the lefthand side of the equation.
True. The only area where a line parallel to one side would be able to intersect both other sides would be in a place that proportionally divides the other sides.
