Solution for X=16+(X-4)*(X+4) equation:


Simplifying
X = 16 + (X + -4)(X + 4)

Reorder the terms:
X = 16 + (-4 + X)(X + 4)

Reorder the terms:
X = 16 + (-4 + X)(4 + X)

Multiply (-4 + X) * (4 + X)
X = 16 + (-4(4 + X) + X(4 + X))
X = 16 + ((4 * -4 + X * -4) + X(4 + X))
X = 16 + ((-16 + -4X) + X(4 + X))
X = 16 + (-16 + -4X + (4 * X + X * X))
X = 16 + (-16 + -4X + (4X + X2))

Combine like terms: -4X + 4X = 0
X = 16 + (-16 + 0 + X2)
X = 16 + (-16 + X2)

Combine like terms: 16 + -16 = 0
X = 0 + X2
X = X2

Solving
X = X2

Solving for variable 'X'.

Combine like terms: X2 + -1X2 = 0
X + -1X2 = 0
