Solution for F(x+y)=f(x)f(y) equation:


Simplifying
F(x + y) = f(x) * f(y)
(x * F + y * F) = f(x) * f(y)
(xF + yF) = f(x) * f(y)

Multiply f * x
xF + yF = fx * f * y

Multiply fx * f
xF + yF = f2x * y

Multiply f2x * y
xF + yF = f2xy

Solving
xF + yF = f2xy

Solving for variable 'x'.

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

Add '-1f2xy' to each side of the equation.
xF + -1f2xy + yF = f2xy + -1f2xy

Reorder the terms:
-1f2xy + xF + yF = f2xy + -1f2xy

Combine like terms: f2xy + -1f2xy = 0
-1f2xy + xF + yF = 0

Add '-1yF' to each side of the equation.
-1f2xy + xF + yF + -1yF = 0 + -1yF

Combine like terms: yF + -1yF = 0
-1f2xy + xF + 0 = 0 + -1yF
-1f2xy + xF = 0 + -1yF
Remove the zero:
-1f2xy + xF = -1yF

Combine like terms: -1yF + yF = 0
-1f2xy + xF + yF = 0

The solution to this equation could not be determined.
