-1(2y-1)(y-1)=

Solution for -1(2y-1)(y-1)= equation:

Simplifying
-1(2y + -1)(y + -1) = 0

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

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

Multiply (-1 + 2y) * (-1 + y)
-1(-1(-1 + y) + 2y * (-1 + y)) = 0
-1((-1 * -1 + y * -1) + 2y * (-1 + y)) = 0
-1((1 + -1y) + 2y * (-1 + y)) = 0
-1(1 + -1y + (-1 * 2y + y * 2y)) = 0
-1(1 + -1y + (-2y + 2y2)) = 0

Combine like terms: -1y + -2y = -3y
-1(1 + -3y + 2y2) = 0
(1 * -1 + -3y * -1 + 2y2 * -1) = 0
(-1 + 3y + -2y2) = 0

Solving
-1 + 3y + -2y2 = 0

Solving for variable 'y'.

Factor a trinomial.

y = 1

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

Simplifying
1 + -2y = 0

Solving
1 + -2y = 0

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

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

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

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

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

Simplifying
y = 0.5
Solution
y = {1, 0.5}
