2(-4u*4-u*u)=

Solution for 2(-4u*4-u*u)= equation:

Simplifying
2(-4u * 4 + -1u * u) = 0

Reorder the terms for easier multiplication:
2(-4 * 4u + -1u * u) = 0

Multiply -4 * 4
2(-16u + -1u * u) = 0

Multiply u * u
2(-16u + -1u2) = 0
(-16u * 2 + -1u2 * 2) = 0
(-32u + -2u2) = 0

Solving
-32u + -2u2 = 0

Solving for variable 'u'.

Factor out the Greatest Common Factor (GCF), '-2u'.
-2u(16 + u) = 0

Ignore the factor -2.
Subproblem 1
Set the factor 'u' equal to zero and attempt to solve:

Simplifying
u = 0

Solving
u = 0

Move all terms containing u to the left, all other terms to the right.

Simplifying
u = 0
Subproblem 2
Set the factor '(16 + u)' equal to zero and attempt to solve:

Simplifying
16 + u = 0

Solving
16 + u = 0

Move all terms containing u to the left, all other terms to the right.

Add '-16' to each side of the equation.
16 + -16 + u = 0 + -16

Combine like terms: 16 + -16 = 0
0 + u = 0 + -16
u = 0 + -16

Combine like terms: 0 + -16 = -16
u = -16

Simplifying
u = -16
Solution
u = {0, -16}
