Simplifying y(2y + -1) = 1 Reorder the terms: y(-1 + 2y) = 1 (-1 * y + 2y * y) = 1 (-1y + 2y2) = 1 Solving -1y + 2y2 = 1 Solving for variable 'y'. Reorder the terms: -1 + -1y + 2y2 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + -1y + 2y2 = 0 Factor a trinomial. (-1 + -2y)(1 + -1y) = 0Subproblem 1
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 = -0.5Subproblem 2
Set the factor '(1 + -1y)' equal to zero and attempt to solve: Simplifying 1 + -1y = 0 Solving 1 + -1y = 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 + -1y = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1y = 0 + -1 -1y = 0 + -1 Combine like terms: 0 + -1 = -1 -1y = -1 Divide each side by '-1'. y = 1 Simplifying y = 1Solution
y = {-0.5, 1}
