(3z-1)(6+z)=0

Solution for (3z-1)(6+z)=0 equation:

Simplifying
(3z + -1)(6 + z) = 0

Reorder the terms:
(-1 + 3z)(6 + z) = 0

Multiply (-1 + 3z) * (6 + z)
(-1(6 + z) + 3z * (6 + z)) = 0
((6 * -1 + z * -1) + 3z * (6 + z)) = 0
((-6 + -1z) + 3z * (6 + z)) = 0
(-6 + -1z + (6 * 3z + z * 3z)) = 0
(-6 + -1z + (18z + 3z2)) = 0

Combine like terms: -1z + 18z = 17z
(-6 + 17z + 3z2) = 0

Solving
-6 + 17z + 3z2 = 0

Solving for variable 'z'.

Factor a trinomial.
(-6 + -1z)(1 + -3z) = 0

Subproblem 1

1 + -1 + -3z = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -3z = 0 + -1
-3z = 0 + -1

Combine like terms: 0 + -1 = -1
-3z = -1

Divide each side by '-3'.
z = 0.3333333333

Simplifying
z = 0.3333333333
Solution
z = {-6, 0.3333333333}
