Solution for F(x)=x^2ln(7x) equation:


Simplifying
F(x) = x2ln(7x)

Multiply F * x
xF = x2ln(7x)

Remove parenthesis around (7x)
xF = lnx2 * 7x

Reorder the terms for easier multiplication:
xF = 7lnx2 * x

Multiply lnx2 * x
xF = 7lnx3

Solving
xF = 7lnx3

Solving for variable 'x'.

Reorder the terms:
-7lnx3 + xF = 7lnx3 + -7lnx3

Combine like terms: 7lnx3 + -7lnx3 = 0
-7lnx3 + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-7lnx2 + F) = 0

Subproblem 1

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

Subproblem 2

Set the factor '(-7lnx2 + F)' equal to zero and attempt to solve: Simplifying -7lnx2 + F = 0 Reorder the terms: F + -7lnx2 = 0 Solving F + -7lnx2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-1F' to each side of the equation. F + -1F + -7lnx2 = 0 + -1F Combine like terms: F + -1F = 0 0 + -7lnx2 = 0 + -1F -7lnx2 = 0 + -1F Remove the zero: -7lnx2 = -1F Divide each side by '-7ln'. x2 = 0.1428571429l-1n-1F Simplifying x2 = 0.1428571429l-1n-1F The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
