Simplifying 2u2 + 8u + 8 = 0 Reorder the terms: 8 + 8u + 2u2 = 0 Solving 8 + 8u + 2u2 = 0 Solving for variable 'u'. Factor out the Greatest Common Factor (GCF), '2'. 2(4 + 4u + u2) = 0 Factor a trinomial. 2((2 + u)(2 + u)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(2 + u)' equal to zero and attempt to solve: Simplifying 2 + u = 0 Solving 2 + u = 0 Move all terms containing u to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + u = 0 + -2 Combine like terms: 2 + -2 = 0 0 + u = 0 + -2 u = 0 + -2 Combine like terms: 0 + -2 = -2 u = -2 Simplifying u = -2Subproblem 2
