Simplifying
F(x) = (x + 4)(4x2 + 3)

Multiply F * x
xF = (x + 4)(4x2 + 3)

Reorder the terms:
xF = (4 + x)(4x2 + 3)

Reorder the terms:
xF = (4 + x)(3 + 4x2)

Multiply (4 + x) * (3 + 4x2)
xF = (4(3 + 4x2) + x(3 + 4x2))
xF = ((3 * 4 + 4x2 * 4) + x(3 + 4x2))
xF = ((12 + 16x2) + x(3 + 4x2))
xF = (12 + 16x2 + (3 * x + 4x2 * x))
xF = (12 + 16x2 + (3x + 4x3))

Reorder the terms:
xF = (12 + 3x + 16x2 + 4x3)
xF = (12 + 3x + 16x2 + 4x3)

Solving
xF = 12 + 3x + 16x2 + 4x3

Solving for variable 'x'.
