Solution for (8-u)(4u-2)=0 equation:


Simplifying
(8 + -1u)(4u + -2) = 0

Reorder the terms:
(8 + -1u)(-2 + 4u) = 0

Multiply (8 + -1u) * (-2 + 4u)
(8(-2 + 4u) + -1u * (-2 + 4u)) = 0
((-2 * 8 + 4u * 8) + -1u * (-2 + 4u)) = 0
((-16 + 32u) + -1u * (-2 + 4u)) = 0
(-16 + 32u + (-2 * -1u + 4u * -1u)) = 0
(-16 + 32u + (2u + -4u2)) = 0

Combine like terms: 32u + 2u = 34u
(-16 + 34u + -4u2) = 0

Solving
-16 + 34u + -4u2 = 0

Solving for variable 'u'.

Factor out the Greatest Common Factor (GCF), '2'.

Subproblem 1

Set the factor '(-8 + u)' equal to zero and attempt to solve: Simplifying -8 + u = 0 Solving -8 + u = 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 + u = 0 + 8 Combine like terms: -8 + 8 = 0 0 + u = 0 + 8 u = 0 + 8 Combine like terms: 0 + 8 = 8 u = 8 Simplifying u = 8

Subproblem 2

Set the factor '(1 + -2u)' equal to zero and attempt to solve: Simplifying 1 + -2u = 0 Solving 1 + -2u = 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 + -2u = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2u = 0 + -1 -2u = 0 + -1 Combine like terms: 0 + -1 = -1 -2u = -1 Divide each side by '-2'. u = 0.5 Simplifying u = 0.5

Solution

u = {8, 0.5}
