Solution for x^2=16+(x-4)(x+4) equation:


Simplifying
x2 = 16 + (x + -4)(x + 4)

Reorder the terms:
x2 = 16 + (-4 + x)(x + 4)

Reorder the terms:
x2 = 16 + (-4 + x)(4 + x)

Multiply (-4 + x) * (4 + x)
x2 = 16 + (-4(4 + x) + x(4 + x))
x2 = 16 + ((4 * -4 + x * -4) + x(4 + x))
x2 = 16 + ((-16 + -4x) + x(4 + x))
x2 = 16 + (-16 + -4x + (4 * x + x * x))
x2 = 16 + (-16 + -4x + (4x + x2))

Combine like terms: -4x + 4x = 0
x2 = 16 + (-16 + 0 + x2)
x2 = 16 + (-16 + x2)
