Simplifying y2 + 3y + -90 = 0 Reorder the terms: -90 + 3y + y2 = 0 Solving -90 + 3y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '90' to each side of the equation. -90 + 3y + 90 + y2 = 0 + 90 Reorder the terms: -90 + 90 + 3y + y2 = 0 + 90 Combine like terms: -90 + 90 = 0 0 + 3y + y2 = 0 + 90 3y + y2 = 0 + 90 Combine like terms: 0 + 90 = 90 3y + y2 = 90 The y term is 3y. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3y + 2.25 + y2 = 90 + 2.25 Reorder the terms: 2.25 + 3y + y2 = 90 + 2.25 Combine like terms: 90 + 2.25 = 92.25 2.25 + 3y + y2 = 92.25 Factor a perfect square on the left side: (y + 1.5)(y + 1.5) = 92.25 Calculate the square root of the right side: 9.604686356 Break this problem into two subproblems by setting (y + 1.5) equal to 9.604686356 and -9.604686356.Subproblem 1
y + 1.5 = 9.604686356 Simplifying y + 1.5 = 9.604686356 Reorder the terms: 1.5 + y = 9.604686356 Solving 1.5 + y = 9.604686356 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + y = 9.604686356 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + y = 9.604686356 + -1.5 y = 9.604686356 + -1.5 Combine like terms: 9.604686356 + -1.5 = 8.104686356 y = 8.104686356 Simplifying y = 8.104686356Subproblem 2
y + 1.5 = -9.604686356 Simplifying y + 1.5 = -9.604686356 Reorder the terms: 1.5 + y = -9.604686356 Solving 1.5 + y = -9.604686356 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + y = -9.604686356 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + y = -9.604686356 + -1.5 y = -9.604686356 + -1.5 Combine like terms: -9.604686356 + -1.5 = -11.104686356 y = -11.104686356 Simplifying y = -11.104686356Solution
