Simplifying (5u2) + 2 = -7u Reorder the terms: 2 + (5u2) = -7u Solving 2 + (5u2) = -7u Solving for variable 'u'. Reorder the terms: 2 + 7u + (5u2) = -7u + 7u Combine like terms: -7u + 7u = 0 2 + 7u + (5u2) = 0 Factor a trinomial. (1 + u)(2 + 5u) = 0Subproblem 1
Set the factor '(1 + u)' equal to zero and attempt to solve: Simplifying 1 + u = 0 Solving 1 + u = 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 + u = 0 + -1 Combine like terms: 1 + -1 = 0 0 + u = 0 + -1 u = 0 + -1 Combine like terms: 0 + -1 = -1 u = -1 Simplifying u = -1Subproblem 2
Set the factor '(2 + 5u)' equal to zero and attempt to solve: Simplifying 2 + 5u = 0 Solving 2 + 5u = 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 + 5u = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 5u = 0 + -2 5u = 0 + -2 Combine like terms: 0 + -2 = -2 5u = -2 Divide each side by '5'. u = -0.4 Simplifying u = -0.4Solution
u = {-1, -0.4}
