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

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

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

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

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

Combine like terms: 5w + 2w = 7w
(-2 + 7w + -5w2) = 0

Solving
-2 + 7w + -5w2 = 0

Solving for variable 'w'.

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

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

Simplifying
-1 + w = 0

Solving
-1 + w = 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 + w = 0 + 1

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

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

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

Simplifying
2 + -5w = 0

Solving
2 + -5w = 0

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

Add '-2' to each side of the equation.
2 + -2 + -5w = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -5w = 0 + -2
-5w = 0 + -2

Combine like terms: 0 + -2 = -2
-5w = -2

Divide each side by '-5'.
w = 0.4

Simplifying
w = 0.4
Solution
w = {1, 0.4}
