Solution for (u+25)(-u-16)=0 equation:


Simplifying
(u + 25)(-1u + -16) = 0

Reorder the terms:
(25 + u)(-1u + -16) = 0

Reorder the terms:
(25 + u)(-16 + -1u) = 0

Multiply (25 + u) * (-16 + -1u)
(25(-16 + -1u) + u(-16 + -1u)) = 0
((-16 * 25 + -1u * 25) + u(-16 + -1u)) = 0
((-400 + -25u) + u(-16 + -1u)) = 0
(-400 + -25u + (-16 * u + -1u * u)) = 0
(-400 + -25u + (-16u + -1u2)) = 0

Combine like terms: -25u + -16u = -41u
(-400 + -41u + -1u2) = 0

Solving
-400 + -41u + -1u2 = 0

Solving for variable 'u'.

-1((25 + u)(16 + u)) = 0

Ignore the factor -1.

Subproblem 1

Set the factor '(25 + u)' equal to zero and attempt to solve: Simplifying 25 + u = 0 Solving 25 + u = 0 Move all terms containing u to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + u = 0 + -25 Combine like terms: 25 + -25 = 0 0 + u = 0 + -25 u = 0 + -25 Combine like terms: 0 + -25 = -25 u = -25 Simplifying u = -25

Subproblem 2

Set the factor '(16 + u)' equal to zero and attempt to solve: Simplifying 16 + u = 0 Solving 16 + u = 0 Move all terms containing u to the left, all other terms to the right. Add '-16' to each side of the equation. 16 + -16 + u = 0 + -16 Combine like terms: 16 + -16 = 0 0 + u = 0 + -16 u = 0 + -16 Combine like terms: 0 + -16 = -16 u = -16 Simplifying u = -16

Solution

u = {-25, -16}
