Forgotten Fractions? Get Guidance Here!

AI Thread Summary
The discussion revolves around solving a complex equation involving fractions and powers of x. A participant initially arrived at an answer of 0.4 but struggled with the fundamentals of fractions and isolating x. Suggestions included using the reciprocal for division, factoring out common terms, and simplifying the equation by reducing terms like 4-2x and 3-3x. Despite attempts to factor and simplify, the participant faced difficulties due to the presence of multiple powers of x, leading to confusion in isolating the variable. The conversation emphasizes the need for a systematic approach to tackle equations with varying degrees of x.

Dividing by something is the same as multiplying by that something's reciprocal.
 
i have tried that but still the power is larger than a quadratic, so i wasnt able to solve it
 
Reduce the 4-2x terms and also with the left over 4-2x you can factor out a common term of 2.

Factor our a common term of 3 in 3-3x and keep going from there.
 
Another tip is to square root both sides to get rid of the even powers larger than 2 after you've done all that.
 
did factor out the 3 it becomes 27, i think
and canceled some of the 4-2x , as you suggested

but the main problem for me is still so much x,
cant really isolate it, because i tried expanding it
and i get like x^1 , x^2, x^3, X^4...
and do not know how to solve those
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
