  1. Great, great post! It’s something I have never thought about, really, but it makes a whole lot of sense. Thanks for sharing maths sample papers

  2. This is really great. Keep it up the good going. Really very great blog this has given me all the information that i needed, good for visiting daily it will increase our knowledge. Best luck for future.

  4. Nice paper....But I have a doubt.
    For the first question, don't you think both option b & d (here both are option b) are right because b*b - 4*a*c=0 in both cases. Please reply as soon as possible. Thankyou.
