(4u + 6)(1 + u) = 0

Reorder the terms:
(6 + 4u)(1 + u) = 0

Multiply (6 + 4u) * (1 + u)
(6(1 + u) + 4u * (1 + u)) = 0
((1 * 6 + u * 6) + 4u * (1 + u)) = 0
((6 + 6u) + 4u * (1 + u)) = 0
(6 + 6u + (1 * 4u + u * 4u)) = 0
(6 + 6u + (4u + 4u2)) = 0

Combine like terms: 6u + 4u = 10u
(6 + 10u + 4u2) = 0

Subproblem 1

Set the factor '(3 + 2u)' equal to zero and attempt to solve: Simplifying 3 + 2u = 0 Solving 3 + 2u = 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 + 2u = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2u = 0 + -3 2u = 0 + -3 Combine like terms: 0 + -3 = -3 2u = -3 Divide each side by '2'. u = -1.5 Simplifying u = -1.5

Subproblem 2

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 = -1

Solution

u = {-1.5, -1}
