Solution for (z-4)(-z+2)(z+8)=0 equation:


Simplifying
(z + -4)(-1z + 2)(z + 8) = 0

Reorder the terms:
(-4 + z)(-1z + 2)(z + 8) = 0

Reorder the terms:
(-4 + z)(2 + -1z)(z + 8) = 0

Reorder the terms:
(-4 + z)(2 + -1z)(8 + z) = 0

Multiply (-4 + z) * (2 + -1z)
(-4(2 + -1z) + z(2 + -1z))(8 + z) = 0
((2 * -4 + -1z * -4) + z(2 + -1z))(8 + z) = 0
((-8 + 4z) + z(2 + -1z))(8 + z) = 0
(-8 + 4z + (2 * z + -1z * z))(8 + z) = 0
(-8 + 4z + (2z + -1z2))(8 + z) = 0

Combine like terms: 4z + 2z = 6z
(-8 + 6z + -1z2)(8 + z) = 0

Multiply (-8 + 6z + -1z2) * (8 + z)
(-8(8 + z) + 6z * (8 + z) + -1z2 * (8 + z)) = 0
((8 * -8 + z * -8) + 6z * (8 + z) + -1z2 * (8 + z)) = 0
((-64 + -8z) + 6z * (8 + z) + -1z2 * (8 + z)) = 0
(-64 + -8z + (8 * 6z + z * 6z) + -1z2 * (8 + z)) = 0
(-64 + -8z + (48z + 6z2) + -1z2 * (8 + z)) = 0
(-64 + -8z + 48z + 6z2 + (8 * -1z2 + z * -1z2)) = 0
(-64 + -8z + 48z + 6z2 + (-8z2 + -1z3)) = 0

Combine like terms: -8z + 48z = 40z
(-64 + 40z + 6z2 + -8z2 + -1z3) = 0

Combine like terms: 6z2 + -8z2 = -2z2
(-64 + 40z + -2z2 + -1z3) = 0

Solving
-64 + 40z + -2z2 + -1z3 = 0

Solving for variable 'z'.
