Solution for (4+u)(4+u)=0 equation:


Simplifying
(4 + u)(4 + u) = 0

Multiply (4 + u) * (4 + u)
(4(4 + u) + u(4 + u)) = 0
((4 * 4 + u * 4) + u(4 + u)) = 0
((16 + 4u) + u(4 + u)) = 0
(16 + 4u + (4 * u + u * u)) = 0
(16 + 4u + (4u + u2)) = 0

Combine like terms: 4u + 4u = 8u
(16 + 8u + u2) = 0

Solving
16 + 8u + u2 = 0
