Solution for F(x)=3(x-4)(x+1) equation: 


Simplifying
F(x) = 3(x + -4)(x + 1)

Multiply F * x
xF = 3(x + -4)(x + 1)

Reorder the terms:
xF = 3(-4 + x)(x + 1)

Reorder the terms:
xF = 3(-4 + x)(1 + x)

Multiply (-4 + x) * (1 + x)
xF = 3(-4(1 + x) + x(1 + x))
xF = 3((1 * -4 + x * -4) + x(1 + x))
xF = 3((-4 + -4x) + x(1 + x))
xF = 3(-4 + -4x + (1 * x + x * x))
xF = 3(-4 + -4x + (1x + x2))

Combine like terms: -4x + 1x = -3x
xF = 3(-4 + -3x + x2)
xF = (-4 * 3 + -3x * 3 + x2 * 3)
xF = (-12 + -9x + 3x2)

Solving
xF = -12 + -9x + 3x2

Solving for variable 'x'.

Reorder the terms:
12 + 9x + xF + -3x2 = -12 + -9x + 3x2 + 12 + 9x + -3x2

Reorder the terms:
12 + 9x + xF + -3x2 = -12 + 12 + -9x + 9x + 3x2 + -3x2

Combine like terms: -12 + 12 = 0
12 + 9x + xF + -3x2 = 0 + -9x + 9x + 3x2 + -3x2
12 + 9x + xF + -3x2 = -9x + 9x + 3x2 + -3x2

Combine like terms: -9x + 9x = 0
12 + 9x + xF + -3x2 = 0 + 3x2 + -3x2
12 + 9x + xF + -3x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
12 + 9x + xF + -3x2 = 0
