Quadratic Equation | |

I have not written for a while for my CAT 2010
students, not because I didn't want to but because the explosive growth of
Totalgadha.com and TathaGat kept me busy in multidimensional roles. Gone are
the long evening walks, leisurely problem-solving sessions and book readings.
Now my time is spent in hurried classroom sessions, editing worksheets,
answering incessant phone calls, and managing a rapidly-growing team. The
pleasures and pains of entrepreneurship are numerous. Not that I am
complaining. It feels good to see that an idea which was once a passing thought
has blossomed into something real. It is heartening to see that you can do a
lot of good in this world. TG.com was once a thought. Now it is a reality. It
would give rise to more realities. Tomorrow, there would be something better
than TG.com. There would be better thoughts. And in the end, it would be the
students who would benefit the most by the new realities. It is reason enough
to rejoice, pain of entrepreneurship notwithstanding.
One more CAT is approaching fast. There is already a tightening in my stomach, a lump in my throat. If I could have my wish, I would want all my students and TGites to clear CAT. But this is not possible, and in the end, life wouldnâ€™t be interesting without a good mix of victories and defeats. No matter what happens on the D-day, I hope that the students donâ€™t stop learning at least. Amen! So here is it ladies and gentlemen, a fruit of painful labour. I shall have to end here and leave the rest of it for my CBT Club students. I shall cover some problems based on this in the CBT Club this week.

Re: Quadratic Equation | |

Hi Raj, y is not a quadratic expression, it is a rational expression in quadratic. How are you applying the rule? Total Gadha |

Hi Jegathiesh,
you are talking about the roots. I am talking about the maximum value.

Re: Quadratic Equation | |

The perimeter of a rectangle is 80m and it,s area is 400m^2.Find its legnth & breadth ?please provide me the solution of this quadratic Equation. |

Re: Quadratic Equation | |

VERY SIMLPE 2(L+B)=80 L+B=40 L*B=400 X^2 -40X+400=0 (X-20)^2=0 L=B=20 HAVE FUN! |

Re: Quadratic Equation | |

i think its an rectangle so both the sides are not equal so ans is 16*25=400 |

Re: Quadratic Equation | |

Hi Sharmil, 16*25=400 correct..but that does not give the perimeter to 80 as 2(16+25)=82.... So the correct answer is a square of 20*20......... |
