F(x)=4sen(2x)

Solution for F(x)=4sen(2x) equation:

Simplifying
F(x) = 4sen(2x)

Multiply F * x
xF = 4sen(2x)

Remove parenthesis around (2x)
xF = 4ens * 2x

Reorder the terms for easier multiplication:
xF = 4 * 2ens * x

Multiply 4 * 2
xF = 8ens * x

Multiply ens * x
xF = 8ensx

Solving
xF = 8ensx

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8ensx' to each side of the equation.
-8ensx + xF = 8ensx + -8ensx

Combine like terms: 8ensx + -8ensx = 0
-8ensx + xF = 0

Factor out the Greatest Common Factor (GCF), 'x'.
x(-8ens + 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 '(-8ens + F)' equal to zero and attempt to solve:

Simplifying
-8ens + F = 0

Reorder the terms:
F + -8ens = 0

Solving
F + -8ens = 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 + -8ens = 0 + -1F

Combine like terms: F + -1F = 0
0 + -8ens = 0 + -1F
-8ens = 0 + -1F
Remove the zero:
-8ens = -1F

Add '8ens' to each side of the equation.
-8ens + 8ens = -1F + 8ens

Combine like terms: -8ens + 8ens = 0
0 = -1F + 8ens

Simplifying
0 = -1F + 8ens
