Solution for Tn=n(5n+4) equation:


Simplifying
Tn = n(5n + 4)

Reorder the terms:
nT = n(4 + 5n)
nT = (4 * n + 5n * n)
nT = (4n + 5n2)

Solving
nT = 4n + 5n2

Solving for variable 'n'.

Reorder the terms:
-4n + nT + -5n2 = 4n + 5n2 + -4n + -5n2

Reorder the terms:
-4n + nT + -5n2 = 4n + -4n + 5n2 + -5n2

Combine like terms: 4n + -4n = 0
-4n + nT + -5n2 = 0 + 5n2 + -5n2
-4n + nT + -5n2 = 5n2 + -5n2

Combine like terms: 5n2 + -5n2 = 0
-4n + nT + -5n2 = 0

Factor out the Greatest Common Factor (GCF), 'n'.
n(-4 + T + -5n) = 0

Subproblem 1

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

Subproblem 2

Set the factor '(-4 + T + -5n)' equal to zero and attempt to solve: Simplifying -4 + T + -5n = 0 Solving -4 + T + -5n = 0 Move all terms containing n to the left, all other terms to the right. Add '4' to each side of the equation. -4 + T + 4 + -5n = 0 + 4 Reorder the terms: -4 + 4 + T + -5n = 0 + 4 Combine like terms: -4 + 4 = 0 0 + T + -5n = 0 + 4 T + -5n = 0 + 4 Combine like terms: 0 + 4 = 4 T + -5n = 4 Add '-1T' to each side of the equation. T + -1T + -5n = 4 + -1T Combine like terms: T + -1T = 0 0 + -5n = 4 + -1T -5n = 4 + -1T Divide each side by '-5'. n = -0.8 + 0.2T Simplifying n = -0.8 + 0.2T

Solution

n = {0, -0.8 + 0.2T}
