1u(1u + -5) + 8u = 1u(1u + 2) + -4

Reorder the terms:
1u(-5 + 1u) + 8u = 1u(1u + 2) + -4
(-5 * 1u + 1u * 1u) + 8u = 1u(1u + 2) + -4
(-5u + 1u2) + 8u = 1u(1u + 2) + -4

Reorder the terms:
-5u + 8u + 1u2 = 1u(1u + 2) + -4

Combine like terms: -5u + 8u = 3u
3u + 1u2 = 1u(1u + 2) + -4

Reorder the terms:
3u + 1u2 = 1u(2 + 1u) + -4
3u + 1u2 = (2 * 1u + 1u * 1u) + -4
3u + 1u2 = (2u + 1u2) + -4

Reorder the terms:
3u + 1u2 = -4 + 2u + 1u2

Add '-1u2' to each side of the equation.
3u + 1u2 + -1u2 = -4 + 2u + 1u2 + -1u2
