Simplifying (8 + u)(5u + -3) = 0 Reorder the terms: (8 + u)(-3 + 5u) = 0 Multiply (8 + u) * (-3 + 5u) (8(-3 + 5u) + u(-3 + 5u)) = 0 ((-3 * 8 + 5u * 8) + u(-3 + 5u)) = 0 ((-24 + 40u) + u(-3 + 5u)) = 0 (-24 + 40u + (-3 * u + 5u * u)) = 0 (-24 + 40u + (-3u + 5u2)) = 0 Combine like terms: 40u + -3u = 37u (-24 + 37u + 5u2) = 0 Solving -24 + 37u + 5u2 = 0 Solving for variable 'u'. Factor a trinomial. (-8 + -1u)(3 + -5u) = 0Subproblem 1
Set the factor '(-8 + -1u)' equal to zero and attempt to solve: Simplifying -8 + -1u = 0 Solving -8 + -1u = 0 Move all terms containing u to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + -1u = 0 + 8 Combine like terms: -8 + 8 = 0 0 + -1u = 0 + 8 -1u = 0 + 8 Combine like terms: 0 + 8 = 8 -1u = 8 Divide each side by '-1'. u = -8 Simplifying u = -8Subproblem 2
Set the factor '(3 + -5u)' equal to zero and attempt to solve: Simplifying 3 + -5u = 0 Solving 3 + -5u = 0 Move all terms containing u to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5u = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -5u = 0 + -3 -5u = 0 + -3 Combine like terms: 0 + -3 = -3 -5u = -3 Divide each side by '-5'. u = 0.6 Simplifying u = 0.6Solution
u = {-8, 0.6}
