x^2=(x-4)(x+4)+16

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

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

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

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

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

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

Reorder the terms:
x2 = -16 + 16 + x2

Combine like terms: -16 + 16 = 0
x2 = 0 + x2
x2 = x2

Add '-1x2' to each side of the equation.
x2 + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
0 = 0
