Solution for (8-z)(4z-6)=0 equation:


Simplifying
(8 + -1z)(4z + -6) = 0

Reorder the terms:
(8 + -1z)(-6 + 4z) = 0

Multiply (8 + -1z) * (-6 + 4z)
(8(-6 + 4z) + -1z * (-6 + 4z)) = 0
((-6 * 8 + 4z * 8) + -1z * (-6 + 4z)) = 0
((-48 + 32z) + -1z * (-6 + 4z)) = 0
(-48 + 32z + (-6 * -1z + 4z * -1z)) = 0
(-48 + 32z + (6z + -4z2)) = 0

Combine like terms: 32z + 6z = 38z
(-48 + 38z + -4z2) = 0

Solving
-48 + 38z + -4z2 = 0

Subproblem 1

Set the factor '(-8 + z)' equal to zero and attempt to solve: Simplifying -8 + z = 0 Solving -8 + z = 0 Move all terms containing z to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + z = 0 + 8 Combine like terms: -8 + 8 = 0 0 + z = 0 + 8 z = 0 + 8 Combine like terms: 0 + 8 = 8 z = 8 Simplifying z = 8

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 = {8, 1.5}
