SOLUTION: (x+y+z)^3. Click here to see ALL problems on Exponents. Question 631629: (x+y+z)^3. Answer by lenny460 (1073) ( Show Source ): You can put this solution on YOUR website! (x+y+z)^3. (x + y + z) (x + y + z) (x + y + z) We multiply using the FOIL Method: x * x = x^2. x * y = xy. x * z = xz. y * x = xy. y * y = y^2. y * z = yz. z * x = xz.
Detailed step by step solution for expand (x+y+z)^3.
Solution. Verified by Toppr. x3 +y3 +z3 −3xyz = (x+y+z)(x2 +y2 +z2 −xy−yz−zx) First take L.H.S. (x+y+z)(x2 +y2 +z2 −xy−yz−zx) To multiply two polynomials, we multiply each monomial of one polynomial (with its sign) by each monomial (with its sign) of the other polynomial.

Feb 8, 2014 · If one believes that the polynomial ring in 3 variables is a unique factorization ring, which it is, then we relatively easily see that both sides vanish when $x=y$ or when $x=z$ or when $y=z$. The constant $3$ can be determined by plugging in $x=0$, $y=1$, and $z=-1$, for example.
Oct 6, 2021 · A linear equation with three variables20 is in standard form if. ax + by + cz = d. where a, b, c, and d are real numbers. For example, 6x + y + 2z = 26 is in standard form. Solving for z, we obtain z = − 3x − 1 2y + 13 and can consider both x and y to be the independent variables.
