Simplifying (u + -1)(u + 7) = 0 Reorder the terms: (-1 + u)(u + 7) = 0 Reorder the terms: (-1 + u)(7 + u) = 0 Multiply (-1 + u) * (7 + u) (-1(7 + u) + u(7 + u)) = 0 ((7 * -1 + u * -1) + u(7 + u)) = 0 ((-7 + -1u) + u(7 + u)) = 0 (-7 + -1u + (7 * u + u * u)) = 0 (-7 + -1u + (7u + u2)) = 0 Combine like terms: -1u + 7u = 6u (-7 + 6u + u2) = 0 Solving -7 + 6u + u2 = 0 Solving for variable 'u'. Factor a trinomial. (-7 + -1u)(1 + -1u) = 0Subproblem 1
Set the factor '(-7 + -1u)' equal to zero and attempt to solve: Simplifying -7 + -1u = 0 Solving -7 + -1u = 0 Move all terms containing u to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1u = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1u = 0 + 7 -1u = 0 + 7 Combine like terms: 0 + 7 = 7 -1u = 7 Divide each side by '-1'. u = -7 Simplifying u = -7Subproblem 2
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 = 1Solution
u = {-7, 1}
