Solution for a(x)=(2x-4)(x-4)2 equation:


Simplifying
a(x) = (2x + -4)(x + -4) * 2

Multiply a * x
ax = (2x + -4)(x + -4) * 2

Reorder the terms:
ax = (-4 + 2x)(x + -4) * 2

Reorder the terms:
ax = (-4 + 2x)(-4 + x) * 2

Reorder the terms for easier multiplication:
ax = 2(-4 + 2x)(-4 + x)

Multiply (-4 + 2x) * (-4 + x)
ax = 2(-4(-4 + x) + 2x * (-4 + x))
ax = 2((-4 * -4 + x * -4) + 2x * (-4 + x))
ax = 2((16 + -4x) + 2x * (-4 + x))
ax = 2(16 + -4x + (-4 * 2x + x * 2x))
ax = 2(16 + -4x + (-8x + 2x2))

Combine like terms: -4x + -8x = -12x
ax = 2(16 + -12x + 2x2)
ax = (16 * 2 + -12x * 2 + 2x2 * 2)
ax = (32 + -24x + 4x2)

Solving
ax = 32 + -24x + 4x2
