Simplifying 3u2 = 2u + 5 Reorder the terms: 3u2 = 5 + 2u Solving 3u2 = 5 + 2u Solving for variable 'u'. Reorder the terms: -5 + -2u + 3u2 = 5 + 2u + -5 + -2u Reorder the terms: -5 + -2u + 3u2 = 5 + -5 + 2u + -2u Combine like terms: 5 + -5 = 0 -5 + -2u + 3u2 = 0 + 2u + -2u -5 + -2u + 3u2 = 2u + -2u Combine like terms: 2u + -2u = 0 -5 + -2u + 3u2 = 0 Factor a trinomial. (-1 + -1u)(5 + -3u) = 0Subproblem 1
Set the factor '(-1 + -1u)' equal to zero and attempt to solve: Simplifying -1 + -1u = 0 Solving -1 + -1u = 0 Move all terms containing u to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + -1u = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1u = 0 + 1 -1u = 0 + 1 Combine like terms: 0 + 1 = 1 -1u = 1 Divide each side by '-1'. u = -1 Simplifying u = -1Subproblem 2
Set the factor '(5 + -3u)' equal to zero and attempt to solve: Simplifying 5 + -3u = 0 Solving 5 + -3u = 0 Move all terms containing u to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -3u = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -3u = 0 + -5 -3u = 0 + -5 Combine like terms: 0 + -5 = -5 -3u = -5 Divide each side by '-3'. u = 1.666666667 Simplifying u = 1.666666667Solution
u = {-1, 1.666666667}
