Solution to Find the Mistakes

After reading all your entries, I do realise that many of you have difficulty with completing the square method. I will re-explain the concept to you again in class one of these days.

The mistakes in the example given is not solely due to the completing square method. There are some mistakes committed due to incorrect algebraic manipulation.

Hint: To know where are the mistakes, TRY to do the algebraic manipulation steps by yourself.

Question: Coordinate Geometry (A-Maths)

To all my 302A students, pls solve this question by Friday 20/7/2007. Submit your solution to Chiu Rong. This is to prepare you for your test on Monday, 23/7/2007.

Question:
The coordinates of the points P and Q are P(-1,10) and Q(2,4).
a. Find the equation of the perpendicular bisector of the line joining P and Q.
b. If the perpendicular bisector of PQ cuts x and y-axes at points H and K, calculate the length of HK, giving your answer correct to 1d.p.
