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

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

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

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

Multiply (-2 + 4z) * (4 + -1z)
(-2(4 + -1z) + 4z * (4 + -1z)) = 0
((4 * -2 + -1z * -2) + 4z * (4 + -1z)) = 0
((-8 + 2z) + 4z * (4 + -1z)) = 0
(-8 + 2z + (4 * 4z + -1z * 4z)) = 0
(-8 + 2z + (16z + -4z2)) = 0

Combine like terms: 2z + 16z = 18z
(-8 + 18z + -4z2) = 0

Solving
-8 + 18z + -4z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-4 + 9z + -2z2) = 0

Factor a trinomial.
2((-4 + z)(1 + -2z)) = 0

Ignore the factor 2.
Subproblem 1
Set the factor '(-4 + z)' equal to zero and attempt to solve:

Simplifying
-4 + z = 0

Solving
-4 + z = 0

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

Add '4' to each side of the equation.
-4 + 4 + z = 0 + 4

Combine like terms: -4 + 4 = 0
0 + z = 0 + 4
z = 0 + 4

Combine like terms: 0 + 4 = 4
z = 4

Simplifying
z = 4
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 = {4, 0.5}
