Solution for f(x)*g(x)=(3x)(x+1) equation:


Simplifying
f(x) * g(x) = (3x)(x + 1)

Multiply f * x
fx * g * x = (3x)(x + 1)

Multiply fx * g
fgx * x = (3x)(x + 1)

Multiply fgx * x
fgx2 = (3x)(x + 1)

Remove parenthesis around (3x)
fgx2 = 3x(x + 1)

Reorder the terms:
fgx2 = 3x(1 + x)
fgx2 = (1 * 3x + x * 3x)
fgx2 = (3x + 3x2)

Solving
fgx2 = 3x + 3x2

Solving for variable 'f'.

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

Divide each side by 'gx2'.
f = 3g-1x-1 + 3g-1

Simplifying
f = 3g-1x-1 + 3g-1

Reorder the terms:
f = 3g-1 + 3g-1x-1
