Solution for 2(u+2)=-6(u+2)(u+1)+(u+1) equation:


Simplifying
2(u + 2) = -6(u + 2)(u + 1) + (u + 1)

Reorder the terms:
2(2 + u) = -6(u + 2)(u + 1) + (u + 1)
(2 * 2 + u * 2) = -6(u + 2)(u + 1) + (u + 1)
(4 + 2u) = -6(u + 2)(u + 1) + (u + 1)

Reorder the terms:
4 + 2u = -6(2 + u)(u + 1) + (u + 1)

Reorder the terms:
4 + 2u = -6(2 + u)(1 + u) + (u + 1)

Multiply (2 + u) * (1 + u)
4 + 2u = -6(2(1 + u) + u(1 + u)) + (u + 1)
4 + 2u = -6((1 * 2 + u * 2) + u(1 + u)) + (u + 1)
4 + 2u = -6((2 + 2u) + u(1 + u)) + (u + 1)
4 + 2u = -6(2 + 2u + (1 * u + u * u)) + (u + 1)
4 + 2u = -6(2 + 2u + (1u + u2)) + (u + 1)

Combine like terms: 2u + 1u = 3u
4 + 2u = -6(2 + 3u + u2) + (u + 1)
4 + 2u = (2 * -6 + 3u * -6 + u2 * -6) + (u + 1)
4 + 2u = (-12 + -18u + -6u2) + (u + 1)

Reorder the terms:
4 + 2u = -12 + -18u + -6u2 + (1 + u)

Remove parenthesis around (1 + u)
4 + 2u = -12 + -18u + -6u2 + 1 + u

Reorder the terms:
4 + 2u = -12 + 1 + -18u + u + -6u2

Combine like terms: -12 + 1 = -11
4 + 2u = -11 + -18u + u + -6u2

Combine like terms: -18u + u = -17u
4 + 2u = -11 + -17u + -6u2

Solving
4 + 2u = -11 + -17u + -6u2

Solving for variable 'u'.

Reorder the terms:
4 + 11 + 2u + 17u + 6u2 = -11 + -17u + -6u2 + 11 + 17u + 6u2
