Solution for (3z^3-5z^2+8)(z+2)=0 equation: 


Simplifying
(3z3 + -5z2 + 8)(z + 2) = 0

Reorder the terms:
(8 + -5z2 + 3z3)(z + 2) = 0

Reorder the terms:
(8 + -5z2 + 3z3)(2 + z) = 0

Multiply (8 + -5z2 + 3z3) * (2 + z)
(8(2 + z) + -5z2 * (2 + z) + 3z3 * (2 + z)) = 0
((2 * 8 + z * 8) + -5z2 * (2 + z) + 3z3 * (2 + z)) = 0
((16 + 8z) + -5z2 * (2 + z) + 3z3 * (2 + z)) = 0
(16 + 8z + (2 * -5z2 + z * -5z2) + 3z3 * (2 + z)) = 0
(16 + 8z + (-10z2 + -5z3) + 3z3 * (2 + z)) = 0
(16 + 8z + -10z2 + -5z3 + (2 * 3z3 + z * 3z3)) = 0
(16 + 8z + -10z2 + -5z3 + (6z3 + 3z4)) = 0
