    Can this be solved?

    $x^y=y^{x-y}$ Can this equation be solved without using logarithms? I've simplified the equation to $(x\cdot y)^y - y^x = 0$ but I have no clue how to proceed $x, y\in \mathbb{N}$

    Hi there you guys can see the problem here PicPaste - 20140824_105133-N1SKFQCV.jpg Actually when I solve it i get something else 16MC/1.5 + 15360 / 4*1.5 + 2MC*4 + (3*60*4^2) / 6 I later get 10,66 MC + 2560 + 8MC + 480 which gives me MC =-162 what have I done wrong if so,could someone...

    How was this solved?

    The question asks me to determine the intersection 3x-y=11 and 3x2-y2 = 47 This is the given answer. y=3x-11 3x2-(3x-11)2=47 3x2 -9x2 +66x-121-47=0 -6x2 + 66x - 168= 0 x2 -11x +28 = 0 ..... and so on The problem I'm having is in line 3. I'm not sure where the '66x' came from?

    Finding all the Zeros of a Polynomial Equation (already solved for two zeros)

    Hi everyone, I cannot seem to figure out how derive the last two zeros of the equation. Directions read 'Solve' : 3x^4 - 4x^3 + 23x^2 - 36x - 36 = 0, given that one zero is 2/3 Using the given zero, I plugged -2/3 into synthetic division which resulted in a remainder of 0, so I changed...
