Simplifying 3x 1y = z Solving 3x 1y = z Solving for variable 'x' Move all terms containing x to the left, all other terms to the right Add 'y' to each side of the equation 3x 1y y = y z Combine like terms 1y y = 0 3x 0 = y z 3x = y z Divide each side by '3' x = y z Simplifying x = 0 What must be subtracted from 4x^42x^36x^22x6 so that the result is exactly divisible by 2x^2x1? \begin{align} x^3y^3z^33xyz\\ &= x^3y^33x^2y3xy^2z^33xyz3x^2y3xy^2\\ &= (xy)^3z^33xy(xyz)\\ &= (xyz)((xy)^2z^2(xy)z)3xy(xyz)\\ &= (xyz)(x^22xyy^2z^2yzxz3xy)\\ &= (xyz)(x^2y^2z^2xyyzzx) \end{align} Share Cite Follow edited Aug 23 at 2140 Someone 134 7 7 bronze badges answered Oct 29 '13 at
x^4y^4z^4 = 25/6 Given { (xyz=1), (x^2y^2z^2=2), (x^3y^3z^3=3) } The elementary symmetric polynomials in x, y and z are xyz, xyyzzx and xyz Once we find these, we can construct any symmetric polynomial in x, y and z We are given xyz, so we just need to derive the other two Note that 2(xyyzzx) = (xyz)^2(x^2y^2z^2) = 1 So xyyzzx = 1/2 Note that 6xyz = (xyzI don't know what you really want to ask , but here is at least a bit of content to this for this formula Since it is homogenous in x,y,z (so all terms have equal degree), you can read it as a description of a object of algebraic geometry eitherBasically, you substitute the value of X, Y, and Z in the given equation X=0 Y=400 Z=600 X^3=(0)^3= Y^3=(400)^3= Z^3=(600)^3= 3*XYZ=3*0*400*600= X^3Y^3Z^33XYZ= =
