(5-w)(2w-1)=0

Solution for (5-w)(2w-1)=0 equation:

Simplifying
(5 + -1w)(2w + -1) = 0

Reorder the terms:
(5 + -1w)(-1 + 2w) = 0

Multiply (5 + -1w) * (-1 + 2w)
(5(-1 + 2w) + -1w * (-1 + 2w)) = 0
((-1 * 5 + 2w * 5) + -1w * (-1 + 2w)) = 0
((-5 + 10w) + -1w * (-1 + 2w)) = 0
(-5 + 10w + (-1 * -1w + 2w * -1w)) = 0
(-5 + 10w + (1w + -2w2)) = 0

Combine like terms: 10w + 1w = 11w
(-5 + 11w + -2w2) = 0

Solving
-5 + 11w + -2w2 = 0

Solving for variable 'w'.

Factor a trinomial.
(-5 + w)(1 + -2w) = 0

Subproblem 1
Set the factor '(-5 + w)' equal to zero and attempt to solve:

Simplifying
-5 + w = 0

Solving
-5 + w = 0

Move all terms containing w to the left, all other terms to the right.

Add '5' to each side of the equation.
-5 + 5 + w = 0 + 5

Combine like terms: -5 + 5 = 0
0 + w = 0 + 5
w = 0 + 5

Combine like terms: 0 + 5 = 5
w = 5

Simplifying
w = 5
Subproblem 2
Set the factor '(1 + -2w)' equal to zero and attempt to solve:

Simplifying
1 + -2w = 0

Solving
1 + -2w = 0

Move all terms containing w to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -2w = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -2w = 0 + -1
-2w = 0 + -1

Combine like terms: 0 + -1 = -1
-2w = -1

Divide each side by '-2'.
w = 0.5

Simplifying
w = 0.5
Solution
w = {5, 0.5}
