Solution for (4z-2)(3-z)=0 equation:


Simplifying
(4z + -2)(3 + -1z) = 0

Reorder the terms:
(-2 + 4z)(3 + -1z) = 0

Multiply (-2 + 4z) * (3 + -1z)
(-2(3 + -1z) + 4z * (3 + -1z)) = 0
((3 * -2 + -1z * -2) + 4z * (3 + -1z)) = 0
((-6 + 2z) + 4z * (3 + -1z)) = 0
(-6 + 2z + (3 * 4z + -1z * 4z)) = 0
(-6 + 2z + (12z + -4z2)) = 0

Combine like terms: 2z + 12z = 14z
(-6 + 14z + -4z2) = 0

Solving
-6 + 14z + -4z2 = 0

Subproblem 1

Set the factor '(-3 + z)' equal to zero and attempt to solve: Simplifying -3 + z = 0 Solving -3 + z = 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 + z = 0 + 3 Combine like terms: -3 + 3 = 0 0 + z = 0 + 3 z = 0 + 3 Combine like terms: 0 + 3 = 3 z = 3 Simplifying z = 3

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 = {3, 0.5}
