Simplifying 4u2 + 39u + -10 = 0 Reorder the terms: -10 + 39u + 4u2 = 0 Solving -10 + 39u + 4u2 = 0 Solving for variable 'u'. Factor a trinomial. (-10 + -1u)(1 + -4u) = 0Subproblem 1
Set the factor '(-10 + -1u)' equal to zero and attempt to solve: Simplifying -10 + -1u = 0 Solving -10 + -1u = 0 Move all terms containing u to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + -1u = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -1u = 0 + 10 -1u = 0 + 10 Combine like terms: 0 + 10 = 10 -1u = 10 Divide each side by '-1'. u = -10 Simplifying u = -10Subproblem 2
Set the factor '(1 + -4u)' equal to zero and attempt to solve: Simplifying 1 + -4u = 0 Solving 1 + -4u = 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 + -4u = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -4u = 0 + -1 -4u = 0 + -1 Combine like terms: 0 + -1 = -1 -4u = -1 Divide each side by '-4'. u = 0.25 Simplifying u = 0.25Solution
u = {-10, 0.25}
