Simplifying y2 + -9y + 18 = y Reorder the terms: 18 + -9y + y2 = y Solving 18 + -9y + y2 = y Solving for variable 'y'. Reorder the terms: 18 + -9y + -1y + y2 = y + -1y Combine like terms: -9y + -1y = -10y 18 + -10y + y2 = y + -1y Combine like terms: y + -1y = 0 18 + -10y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '-18' to each side of the equation. 18 + -10y + -18 + y2 = 0 + -18 Reorder the terms: 18 + -18 + -10y + y2 = 0 + -18 Combine like terms: 18 + -18 = 0 0 + -10y + y2 = 0 + -18 -10y + y2 = 0 + -18 Combine like terms: 0 + -18 = -18 -10y + y2 = -18 The y term is -10y. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10y + 25 + y2 = -18 + 25 Reorder the terms: 25 + -10y + y2 = -18 + 25 Combine like terms: -18 + 25 = 7 25 + -10y + y2 = 7 Factor a perfect square on the left side: (y + -5)(y + -5) = 7 Calculate the square root of the right side: 2.645751311 Break this problem into two subproblems by setting (y + -5) equal to 2.645751311 and -2.645751311.Subproblem 1
y + -5 = 2.645751311 Simplifying y + -5 = 2.645751311 Reorder the terms: -5 + y = 2.645751311 Solving -5 + y = 2.645751311 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + y = 2.645751311 + 5 Combine like terms: -5 + 5 = 0 0 + y = 2.645751311 + 5 y = 2.645751311 + 5 Combine like terms: 2.645751311 + 5 = 7.645751311 y = 7.645751311 Simplifying y = 7.645751311Subproblem 2
