Solution for F(x)=3(x+6)(x-12) equation: 


Simplifying
F(x) = 3(x + 6)(x + -12)

Multiply F * x
xF = 3(x + 6)(x + -12)

Reorder the terms:
xF = 3(6 + x)(x + -12)

Reorder the terms:
xF = 3(6 + x)(-12 + x)

Multiply (6 + x) * (-12 + x)
xF = 3(6(-12 + x) + x(-12 + x))
xF = 3((-12 * 6 + x * 6) + x(-12 + x))
xF = 3((-72 + 6x) + x(-12 + x))
xF = 3(-72 + 6x + (-12 * x + x * x))
xF = 3(-72 + 6x + (-12x + x2))

Combine like terms: 6x + -12x = -6x
xF = 3(-72 + -6x + x2)
xF = (-72 * 3 + -6x * 3 + x2 * 3)
xF = (-216 + -18x + 3x2)

Solving
xF = -216 + -18x + 3x2

Solving for variable 'x'.

Reorder the terms:
216 + 18x + xF + -3x2 = -216 + -18x + 3x2 + 216 + 18x + -3x2

Reorder the terms:
216 + 18x + xF + -3x2 = -216 + 216 + -18x + 18x + 3x2 + -3x2

Combine like terms: -216 + 216 = 0
216 + 18x + xF + -3x2 = 0 + -18x + 18x + 3x2 + -3x2
216 + 18x + xF + -3x2 = -18x + 18x + 3x2 + -3x2

Combine like terms: -18x + 18x = 0
216 + 18x + xF + -3x2 = 0 + 3x2 + -3x2
216 + 18x + xF + -3x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
216 + 18x + xF + -3x2 = 0
