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

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

Simplifying
(4z + -6)(4 + -1z) = 0

Reorder the terms:
(-6 + 4z)(4 + -1z) = 0

Multiply (-6 + 4z) * (4 + -1z)
(-6(4 + -1z) + 4z * (4 + -1z)) = 0
((4 * -6 + -1z * -6) + 4z * (4 + -1z)) = 0
((-24 + 6z) + 4z * (4 + -1z)) = 0
(-24 + 6z + (4 * 4z + -1z * 4z)) = 0
(-24 + 6z + (16z + -4z2)) = 0

Combine like terms: 6z + 16z = 22z
(-24 + 22z + -4z2) = 0

Solving
-24 + 22z + -4z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-12 + 11z + -2z2) = 0

Factor a trinomial.
2((-4 + z)(3 + -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 '(3 + -2z)' equal to zero and attempt to solve:

Simplifying
3 + -2z = 0

Solving
3 + -2z = 0

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

Add '-3' to each side of the equation.
3 + -3 + -2z = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -2z = 0 + -3
-2z = 0 + -3

Combine like terms: 0 + -3 = -3
-2z = -3

Divide each side by '-2'.
z = 1.5

Simplifying
z = 1.5
Solution
z = {4, 1.5}
