Solution for (u+2)(u+2)=0 equation:


Simplifying
(u + 2)(u + 2) = 0

Reorder the terms:
(2 + u)(u + 2) = 0

Reorder the terms:
(2 + u)(2 + u) = 0

Multiply (2 + u) * (2 + u)
(2(2 + u) + u(2 + u)) = 0
((2 * 2 + u * 2) + u(2 + u)) = 0
((4 + 2u) + u(2 + u)) = 0
(4 + 2u + (2 * u + u * u)) = 0
(4 + 2u + (2u + u2)) = 0

Combine like terms: 2u + 2u = 4u
(4 + 4u + u2) = 0

Solving
4 + 4u + u2 = 0
