Solution for (7z-x)(z^3-7z^2+5zx^2-x^3)= equation: 


Simplifying
(7z + -1x)(z3 + -7z2 + 5zx2 + -1x3) = 0

Reorder the terms:
(-1x + 7z)(z3 + -7z2 + 5zx2 + -1x3) = 0

Reorder the terms:
(-1x + 7z)(5x2z + -1x3 + -7z2 + z3) = 0

Multiply (-1x + 7z) * (5x2z + -1x3 + -7z2 + z3)
(-1x * (5x2z + -1x3 + -7z2 + z3) + 7z * (5x2z + -1x3 + -7z2 + z3)) = 0
((5x2z * -1x + -1x3 * -1x + -7z2 * -1x + z3 * -1x) + 7z * (5x2z + -1x3 + -7z2 + z3)) = 0

Reorder the terms:
((7xz2 + -1xz3 + -5x3z + 1x4) + 7z * (5x2z + -1x3 + -7z2 + z3)) = 0
((7xz2 + -1xz3 + -5x3z + 1x4) + 7z * (5x2z + -1x3 + -7z2 + z3)) = 0
(7xz2 + -1xz3 + -5x3z + 1x4 + (5x2z * 7z + -1x3 * 7z + -7z2 * 7z + z3 * 7z)) = 0
(7xz2 + -1xz3 + -5x3z + 1x4 + (35x2z2 + -7x3z + -49z3 + 7z4)) = 0

Reorder the terms:
(7xz2 + -1xz3 + 35x2z2 + -5x3z + -7x3z + 1x4 + -49z3 + 7z4) = 0

Combine like terms: -5x3z + -7x3z = -12x3z
(7xz2 + -1xz3 + 35x2z2 + -12x3z + 1x4 + -49z3 + 7z4) = 0
