Solution for =3z(8-5z) equation:


Simplifying
0 = 3z(8 + -5z)
0 = (8 * 3z + -5z * 3z)
0 = (24z + -15z2)

Solving
0 = 24z + -15z2

Solving for variable 'z'.
Remove the zero:
-24z + 15z2 = 24z + -15z2 + -24z + 15z2

Reorder the terms:
-24z + 15z2 = 24z + -24z + -15z2 + 15z2

Combine like terms: 24z + -24z = 0
-24z + 15z2 = 0 + -15z2 + 15z2
-24z + 15z2 = -15z2 + 15z2

Combine like terms: -15z2 + 15z2 = 0
-24z + 15z2 = 0

Factor out the Greatest Common Factor (GCF), '3z'.
3z(-8 + 5z) = 0

Ignore the factor 3.

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 '(-8 + 5z)' equal to zero and attempt to solve: Simplifying -8 + 5z = 0 Solving -8 + 5z = 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 + 5z = 0 + 8 Combine like terms: -8 + 8 = 0 0 + 5z = 0 + 8 5z = 0 + 8 Combine like terms: 0 + 8 = 8 5z = 8 Divide each side by '5'. z = 1.6 Simplifying z = 1.6

Solution

z = {0, 1.6}
