X 3 − 3 y z x y 3 z 3 Find one factor of the form x^ {k}m, where x^ {k} divides the monomial with the highest power x^ {3} and m divides the constant factor y^ {3}z^ {3} One such factor is xyz Factor the polynomial by dividing it by this factor Notice that each term is a perfect cube x^3 y^3 = (xy)^3 So we have a sum of cubes, and the factoring formula is a^3 b^3 = (ab)(a^2abb^2) So we use a = xy and b = z to get x^3 y^3 z^3 = (xy)^3 z^3 = ((xy) z)((xy)^2(xy)zz^2) =(xy z)(x^2 y^2 xyz z^2) check by multiplying it out to make sure!

Transcript Ex 25, 13 If x y z = 0, show that x3 y3 z3 = 3xyz We know that x3 y3 z3 3xyz = (x y z) (x2 y2 z2 xy yz zx) Putting x y z = 0, x3 y3 z3 3xyz = (0) (x2 y2 z2 xy yz zx) x3 y3 z3 3xyz = 0 x3 y3 z3 = 3xyz Hence proved Article by In this question formula a 3 b 3 c 3 3abc = (abc)(a 2 b 2 c 2 abbcca) is used LHS part (xy) 3 (yz) 3 (zx) 3 3(xy)(yz)(zx) =(xy yz zxRewrite the expression x y z = 3 ⋅ a x y z = 3 ⋅ a xy z = 3a x y z = 3 a Move all terms not containing y y to the right side of the equation Tap for more steps Subtract x x from both sides of the equation y z = 3 a − x y z = 3 a x Subtract z z from both sides of the equation y = 3 a − x − z y = 3 a x z

(xyz)^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 = xySuppose we wish to find an infinite set of solutions of the equation x^3 x y^3 y = z^3 z (1)where x, y, z are integers greater than 1 If z and x are both odd or both even, we can define integers u and v such that z=uv and x=uv Substituting into equation (1) gives y^3 y = 2v(3u^2 v^2 1)Since v divides the righthand side, it would be nice if it alsodivides the lefthand side,X^3 y^3 z^3
