Simplifying y2 + 2y + -300 = 0 Reorder the terms: -300 + 2y + y2 = 0 Solving -300 + 2y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '300' to each side of the equation. -300 + 2y + 300 + y2 = 0 + 300 Reorder the terms: -300 + 300 + 2y + y2 = 0 + 300 Combine like terms: -300 + 300 = 0 0 + 2y + y2 = 0 + 300 2y + y2 = 0 + 300 Combine like terms: 0 + 300 = 300 2y + y2 = 300 The y term is 2y. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2y + 1 + y2 = 300 + 1 Reorder the terms: 1 + 2y + y2 = 300 + 1 Combine like terms: 300 + 1 = 301 1 + 2y + y2 = 301 Factor a perfect square on the left side: (y + 1)(y + 1) = 301 Calculate the square root of the right side: 17.349351573 Break this problem into two subproblems by setting (y + 1) equal to 17.349351573 and -17.349351573.Subproblem 1
y + 1 = 17.349351573 Simplifying y + 1 = 17.349351573 Reorder the terms: 1 + y = 17.349351573 Solving 1 + y = 17.349351573 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + y = 17.349351573 + -1 Combine like terms: 1 + -1 = 0 0 + y = 17.349351573 + -1 y = 17.349351573 + -1 Combine like terms: 17.349351573 + -1 = 16.349351573 y = 16.349351573 Simplifying y = 16.349351573Subproblem 2
y + 1 = -17.349351573 Simplifying y + 1 = -17.349351573 Reorder the terms: 1 + y = -17.349351573 Solving 1 + y = -17.349351573 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + y = -17.349351573 + -1 Combine like terms: 1 + -1 = 0 0 + y = -17.349351573 + -1 y = -17.349351573 + -1 Combine like terms: -17.349351573 + -1 = -18.349351573 y = -18.349351573 Simplifying y = -18.349351573Solution
The solution to the problem is based on the solutions from the subproblems. y = {16.349351573, -18.349351573}
