(4z-2)(6+z)=0

Solution for (4z-2)(6+z)=0 equation:

Simplifying
(4z + -2)(6 + z) = 0

Reorder the terms:
(-2 + 4z)(6 + z) = 0

Multiply (-2 + 4z) * (6 + z)
(-2(6 + z) + 4z * (6 + z)) = 0
((6 * -2 + z * -2) + 4z * (6 + z)) = 0
((-12 + -2z) + 4z * (6 + z)) = 0
(-12 + -2z + (6 * 4z + z * 4z)) = 0
(-12 + -2z + (24z + 4z2)) = 0

Combine like terms: -2z + 24z = 22z
(-12 + 22z + 4z2) = 0

Solving
-12 + 22z + 4z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-6 + 11z + 2z2) = 0

Factor a trinomial.

Subproblem 1
Set the factor '(-6 + -1z)' equal to zero and attempt to solve:

Simplifying
-6 + -1z = 0

Solving
-6 + -1z = 0

Move all terms containing z to the left, all other terms to the right.

Add '6' to each side of the equation.
-6 + 6 + -1z = 0 + 6

Combine like terms: -6 + 6 = 0
0 + -1z = 0 + 6
-1z = 0 + 6

Combine like terms: 0 + 6 = 6
-1z = 6

Divide each side by '-1'.
z = -6

Simplifying
z = -6
Subproblem 2
Set the factor '(1 + -2z)' equal to zero and attempt to solve:

Simplifying
1 + -2z = 0

Solving
1 + -2z = 0

Move all terms containing z to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -2z = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2z = 0 + -1
-2z = 0 + -1

Combine like terms: 0 + -1 = -1
-2z = -1

Divide each side by '-2'.
z = 0.5

Simplifying
z = 0.5
Solution
z = {-6, 0.5}
