Simplifying u2 = 18u Solving u2 = 18u Solving for variable 'u'. Reorder the terms: -18u + u2 = 18u + -18u Combine like terms: 18u + -18u = 0 -18u + u2 = 0 Factor out the Greatest Common Factor (GCF), 'u'. u(-18 + u) = 0Subproblem 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 '(-18 + u)' equal to zero and attempt to solve: Simplifying -18 + u = 0 Solving -18 + u = 0 Move all terms containing u to the left, all other terms to the right. Add '18' to each side of the equation. -18 + 18 + u = 0 + 18 Combine like terms: -18 + 18 = 0 0 + u = 0 + 18 u = 0 + 18 Combine like terms: 0 + 18 = 18 u = 18 Simplifying u = 18Solution
u = {0, 18}
