Solution for F(x)=(x-4)(x-8) equation: 


Simplifying
F(x) = (x + -4)(x + -8)

Multiply F * x
xF = (x + -4)(x + -8)

Reorder the terms:
xF = (-4 + x)(x + -8)

Reorder the terms:
xF = (-4 + x)(-8 + x)

Multiply (-4 + x) * (-8 + x)
xF = (-4(-8 + x) + x(-8 + x))
xF = ((-8 * -4 + x * -4) + x(-8 + x))
xF = ((32 + -4x) + x(-8 + x))
xF = (32 + -4x + (-8 * x + x * x))
xF = (32 + -4x + (-8x + x2))

Combine like terms: -4x + -8x = -12x
xF = (32 + -12x + x2)

Solving
xF = 32 + -12x + x2

Solving for variable 'x'.

Reorder the terms:
-32 + 12x + xF + -1x2 = 32 + -12x + x2 + -32 + 12x + -1x2

Reorder the terms:
-32 + 12x + xF + -1x2 = 32 + -32 + -12x + 12x + x2 + -1x2

Combine like terms: 32 + -32 = 0
-32 + 12x + xF + -1x2 = 0 + -12x + 12x + x2 + -1x2
-32 + 12x + xF + -1x2 = -12x + 12x + x2 + -1x2

Combine like terms: -12x + 12x = 0
-32 + 12x + xF + -1x2 = 0 + x2 + -1x2
-32 + 12x + xF + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-32 + 12x + xF + -1x2 = 0
