Simplifying 39u = 9u2 Solving 39u = 9u2 Solving for variable 'u'. Combine like terms: 9u2 + -9u2 = 0 39u + -9u2 = 0 Factor out the Greatest Common Factor (GCF), '3u'. 3u(13 + -3u) = 0 Ignore the factor 3.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 = 0Subproblem 2
Set the factor '(13 + -3u)' equal to zero and attempt to solve: Simplifying 13 + -3u = 0 Solving 13 + -3u = 0 Move all terms containing u to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + -3u = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -3u = 0 + -13 -3u = 0 + -13 Combine like terms: 0 + -13 = -13 -3u = -13 Divide each side by '-3'. u = 4.333333333 Simplifying u = 4.333333333Solution
u = {0, 4.333333333}
