my work so far
Thank you for your response. Here is my work so far.
((a^3-b^3)/(a^2-2ab+b^2))/((2a^2+2ab+2b^2)/(9a^2-9b^2))
((a^3-b^3)/(a^2-2ab+b^2))*((9a^2-9b^2)/(2a^2+2ab+2b^2))
((a-b)(a^2+2ab+b^2)/(a^2-2ab+b^2))*((9a^2-9b^2)/(2a^2+2ab+2b^2))...
Homework Statement
((a^3-b^3)/(a^2-2ab+b^2))/((2a^2+2ab+2b^2)/(9a^2-9b^2))
Not using complex number system.
Not concerned with domain.
Find the quotient and put it in simplest terms.

The Attempt at a Solution
Too many to transcribe. Apparently I'm missing...
I'm sorry, Olivermsun, you were correct!
I did not transcribe the problem properly.
Chronon, the error you suspect is the error I made when transcribing.
(embarrassment!)
Olivermsun, your insight is brilliant - particularly your ability to get rid of the decimals in -2.6=17x! I will keep this in mind.
However, I'm afraid that in this case it has produced an erroneous result. x=-13/85 does not check. The only real solution to this equation is x=-103/85. Perhaps...
Jack21222, perhaps I was unclear. I'm sorry about that.
Olivermsun, I can give you an example.
This problem took me at least 15 minutes to solve and check.
0.03x-0.02=0.2(x+0.03)
Maybe it shouldn't have taken me so long. I admit that I'm not great at math.
I am making my way through a Precalculus text. It is not for a class, just independent study. I am doing every problem in the book. So far, I have done all of the problems without a calculator to better my arithmetic skills. This is frequently time consuming because the book isn't giving me...
Mark44 and mege, thank you for your guidance.
How helpful you both have been! Mege, your suggestion is wonderful. That is a skill I'm adding to my list and will not forget.
This question was my first post on physicsforums.com and I am impressed by and thankful for the responses.
Thank you for...
Homework Statement
solve for x:
5|7-3x|+2=4|7-3x|-1
Homework Equations
The Attempt at a Solution
7-3x>0
-3x>-7
x<3/7
{x|x<3/7} quantity is positive
{x|x>3/7} quantity is negative
I have never solved an equation with more than one absolute value quantity in it and am not sure how to start...
