Simplifying y2 + -20y + -1 = 0 Reorder the terms: -1 + -20y + y2 = 0 Solving -1 + -20y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + -20y + 1 + y2 = 0 + 1 Reorder the terms: -1 + 1 + -20y + y2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -20y + y2 = 0 + 1 -20y + y2 = 0 + 1 Combine like terms: 0 + 1 = 1 -20y + y2 = 1 The y term is -20y. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20y + 100 + y2 = 1 + 100 Reorder the terms: 100 + -20y + y2 = 1 + 100 Combine like terms: 1 + 100 = 101 100 + -20y + y2 = 101 Factor a perfect square on the left side: (y + -10)(y + -10) = 101 Calculate the square root of the right side: 10.049875621 Break this problem into two subproblems by setting (y + -10) equal to 10.049875621 and -10.049875621.Subproblem 1
y + -10 = 10.049875621 Simplifying y + -10 = 10.049875621 Reorder the terms: -10 + y = 10.049875621 Solving -10 + y = 10.049875621 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + y = 10.049875621 + 10 Combine like terms: -10 + 10 = 0 0 + y = 10.049875621 + 10 y = 10.049875621 + 10 Combine like terms: 10.049875621 + 10 = 20.049875621 y = 20.049875621 Simplifying y = 20.049875621Subproblem 2
y + -10 = -10.049875621 Simplifying y + -10 = -10.049875621 Reorder the terms: -10 + y = -10.049875621 Solving -10 + y = -10.049875621 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + y = -10.049875621 + 10 Combine like terms: -10 + 10 = 0 0 + y = -10.049875621 + 10 y = -10.049875621 + 10 Combine like terms: -10.049875621 + 10 = -0.049875621 y = -0.049875621 Simplifying y = -0.049875621Solution
