Find the truth set of the following.I have solved the following, but it seems impossible to factorise at some point: #3 20130723 01:39:13
Re: Find the truth set of the following.There is no bracket involved in it from where I copied. #4 20130723 02:02:28
Re: Find the truth set of the following.Here I go. #6 20130723 02:17:12
Re: Find the truth set of the following.Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #7 20130723 02:54:57
Re: Find the truth set of the following.I have solved a similar question successfuly, see. Last edited by EbenezerSon (20130723 05:30:52) #8 20130723 03:00:04

Re: Find the truth set of the following.That is how it exist in the book I am working with. #10 20130723 03:22:38

Re: Find the truth set of the following.
It means the 3 has raised to the power 2x+3. #13 20130723 04:44:58
Re: Find the truth set of the following.Hasn't he raised a good point with
I would agree, but you say it is there! But then his post #5 is correct and that is not a solution. In mathematics, you don't understand things. You just get used to them.

Re: Find the truth set of the following.
The book did not use the symbol ^, I rather used it , because the 2x +3 is at the top of the 3 in the book. #15 20130723 04:58:21
Re: Find the truth set of the following.Hi; This is exactly what is in the book then? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #16 20130723 05:00:19
Re: Find the truth set of the following.
Yes that's how it is arranged, in the book. Last edited by EbenezerSon (20130723 05:03:09) #17 20130723 05:01:28
Re: Find the truth set of the following.
Yes Sir!. Positive 1 is at the end Last edited by EbenezerSon (20130723 05:03:46) #18 20130723 05:04:42
Re: Find the truth set of the following.It is obviously some sort of typo. In mathematics, you don't understand things. You just get used to them.

Re: Find the truth set of the following.
The book is before me now and has positive 1 just at the end. Last edited by EbenezerSon (20130723 06:25:55) #20 20130723 05:35:04
Re: Find the truth set of the following.It still looks like a mistake in the book. 1 and 2 are not roots of that equation. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #21 20130723 05:45:58
Re: Find the truth set of the following.Then please how exactly would the final answer be? #22 20130723 05:53:41
Re: Find the truth set of the following.I could not solve that by hand. It takes a computer to solve it. The answer involves complex numbers further showing that the problem is mistyped.

Re: Find the truth set of the following.Yeb I must believe you, c'os the author stated explicitly that, a student should forgive any mistake that would be found in the book. Is just at the beginning of the book . Last edited by EbenezerSon (20130723 06:53:35) #24 20130723 06:55:23
Re: Find the truth set of the following.If you are marked wrong about it then you will have the consolation of knowing that I would have been marked wrong too.

Re: Find the truth set of the following.So now the question has become: It still will not lead to those answers: x = 1 x = 2 Closest equation with those answers that I can find: Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei
