Solution for f(x)=(x^2+2)(3x-1) equation: 


Simplifying
f(x) = (x2 + 2)(3x + -1)

Multiply f * x
fx = (x2 + 2)(3x + -1)

Reorder the terms:
fx = (2 + x2)(3x + -1)

Reorder the terms:
fx = (2 + x2)(-1 + 3x)

Multiply (2 + x2) * (-1 + 3x)
fx = (2(-1 + 3x) + x2(-1 + 3x))
fx = ((-1 * 2 + 3x * 2) + x2(-1 + 3x))
fx = ((-2 + 6x) + x2(-1 + 3x))
fx = (-2 + 6x + (-1 * x2 + 3x * x2))
fx = (-2 + 6x + (-1x2 + 3x3))
fx = (-2 + 6x + -1x2 + 3x3)

Solving
fx = -2 + 6x + -1x2 + 3x3
