AI Thread Summary
To solve the equation 4x^2 - 2xy + 3y^2 = 2 in terms of y, first rearrange it to 4x^2 - 2xy = 2 - 3y^2. This can be treated as a quadratic equation in y, where a = 3, b = -2x, and c = 4x^2 - 2. Alternatively, if solving for x in terms of y, treat it as a quadratic with a = 4, b = -2y, and c = 3y^2. Incorporating the constant 2 into the equation allows for proper quadratic formulation.

View the equation as a quadratic ##ay^2+by+c=0## with ##a=3, b=-2x, c=4x^2##, that is if you want to find ##y=f(x)##.
if you want to find ##x=f(y)## then view it as a quadratic ##ax^2+bx+c=0## with ##a=4,b=-2y, c=3y^2##.
 
What do I do with the 2 at the end of the original equation?

Please include a complete statement of your problem in the text of the post itself, no matter what you state in the title.

Ah yes sorry, I thought it was =0, just incorporate 2 inside c, so ##c=4x^2-2## (or ##c=3y^2-2##)
 
Ah! Well that's going to be fun! Thank you so much!
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
