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


Simplifying
2z(z + 4) + 3(z2 + -1z) = 0

Reorder the terms:
2z(4 + z) + 3(z2 + -1z) = 0
(4 * 2z + z * 2z) + 3(z2 + -1z) = 0
(8z + 2z2) + 3(z2 + -1z) = 0

Reorder the terms:
8z + 2z2 + 3(-1z + z2) = 0
8z + 2z2 + (-1z * 3 + z2 * 3) = 0
8z + 2z2 + (-3z + 3z2) = 0

Reorder the terms:
8z + -3z + 2z2 + 3z2 = 0

Combine like terms: 8z + -3z = 5z
5z + 2z2 + 3z2 = 0

Combine like terms: 2z2 + 3z2 = 5z2
5z + 5z2 = 0

Solving
5z + 5z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '5z'.

Ignore the factor 5.

Subproblem 1

Set the factor 'z' equal to zero and attempt to solve: Simplifying z = 0 Solving z = 0 Move all terms containing z to the left, all other terms to the right. Simplifying z = 0

Subproblem 2

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

Solution

z = {0, -1}
