Solution for (4z-6)(1+z)=0 equation:


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

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

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

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

Solving
-6 + -2z + 4z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-3 + -1z + 2z2) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(-1 + -1z)' equal to zero and attempt to solve: Simplifying -1 + -1z = 0 Solving -1 + -1z = 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 + -1z = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1z = 0 + 1 -1z = 0 + 1 Combine like terms: 0 + 1 = 1 -1z = 1 Divide each side by '-1'. z = -1 Simplifying z = -1

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 = {-1, 1.5}
