Solution for g(x)=(x^2+4x-12)(x-3) equation:


Simplifying
g(x) = (x2 + 4x + -12)(x + -3)

Multiply g * x
gx = (x2 + 4x + -12)(x + -3)

Reorder the terms:
gx = (-12 + 4x + x2)(x + -3)

Reorder the terms:
gx = (-12 + 4x + x2)(-3 + x)

Multiply (-12 + 4x + x2) * (-3 + x)
gx = (-12(-3 + x) + 4x * (-3 + x) + x2(-3 + x))
gx = ((-3 * -12 + x * -12) + 4x * (-3 + x) + x2(-3 + x))
gx = ((36 + -12x) + 4x * (-3 + x) + x2(-3 + x))
gx = (36 + -12x + (-3 * 4x + x * 4x) + x2(-3 + x))
gx = (36 + -12x + (-12x + 4x2) + x2(-3 + x))
gx = (36 + -12x + -12x + 4x2 + (-3 * x2 + x * x2))
gx = (36 + -12x + -12x + 4x2 + (-3x2 + x3))

Combine like terms: -12x + -12x = -24x
gx = (36 + -24x + 4x2 + -3x2 + x3)

Combine like terms: 4x2 + -3x2 = 1x2
gx = (36 + -24x + 1x2 + x3)

Solving
gx = 36 + -24x + 1x2 + x3

Solving for variable 'g'.
