Solution for 108=x(x-3)(x-7) equation: 


Simplifying
108 = x(x + -3)(x + -7)

Reorder the terms:
108 = x(-3 + x)(x + -7)

Reorder the terms:
108 = x(-3 + x)(-7 + x)

Multiply (-3 + x) * (-7 + x)
108 = x(-3(-7 + x) + x(-7 + x))
108 = x((-7 * -3 + x * -3) + x(-7 + x))
108 = x((21 + -3x) + x(-7 + x))
108 = x(21 + -3x + (-7 * x + x * x))
108 = x(21 + -3x + (-7x + x2))

Combine like terms: -3x + -7x = -10x
108 = x(21 + -10x + x2)
108 = (21 * x + -10x * x + x2 * x)
108 = (21x + -10x2 + x3)

Solving
108 = 21x + -10x2 + x3

Solving for variable 'x'.

Reorder the terms:
108 + -21x + 10x2 + -1x3 = 21x + -21x + -10x2 + 10x2 + x3 + -1x3
