Is this the gratitude I get in return?

scientia ,if you can read English and understand it then look at post #4 ,I appreciated your work ,I thanked you...

Doing the sum is nothing its simple....

Maybe what you don't understand is not the question but the English language?

Yes, in general I speak English and understand it properly, but this question is not very much clear and I think bobbym also agreed with me on #7

My main question on post #1 was about clarification of the question elaborately ,I was not asking about the solution.

If somebody ask you --- What the question is asking for ? Find the roots of equation

.

And you just solve the equation ,that what you did in my case ,will not answer his/her question, you need to explain him/her what does the roots means in an quadratic equation.

You knew what I asked for... but you yourself don’t understand the question clearly, posting the solution doesn’t means you know about it, their are many books where you will find this question and its solution.

Now the main thing, please please please please never ever try to help me again in future ,just stick with your bed and have good dreams...
