Simplifying y2 + 99y + 620 = 0 Reorder the terms: 620 + 99y + y2 = 0 Solving 620 + 99y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-620' to each side of the equation. 620 + 99y + -620 + y2 = 0 + -620 Reorder the terms: 620 + -620 + 99y + y2 = 0 + -620 Combine like terms: 620 + -620 = 0 0 + 99y + y2 = 0 + -620 99y + y2 = 0 + -620 Combine like terms: 0 + -620 = -620 99y + y2 = -620 The y term is 99y. Take half its coefficient (49.5). Square it (2450.25) and add it to both sides. Add '2450.25' to each side of the equation. 99y + 2450.25 + y2 = -620 + 2450.25 Reorder the terms: 2450.25 + 99y + y2 = -620 + 2450.25 Combine like terms: -620 + 2450.25 = 1830.25 2450.25 + 99y + y2 = 1830.25 Factor a perfect square on the left side: (y + 49.5)(y + 49.5) = 1830.25 Calculate the square root of the right side: 42.781421201 Break this problem into two subproblems by setting (y + 49.5) equal to 42.781421201 and -42.781421201.Subproblem 1
y + 49.5 = 42.781421201 Simplifying y + 49.5 = 42.781421201 Reorder the terms: 49.5 + y = 42.781421201 Solving 49.5 + y = 42.781421201 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-49.5' to each side of the equation. 49.5 + -49.5 + y = 42.781421201 + -49.5 Combine like terms: 49.5 + -49.5 = 0.0 0.0 + y = 42.781421201 + -49.5 y = 42.781421201 + -49.5 Combine like terms: 42.781421201 + -49.5 = -6.718578799 y = -6.718578799 Simplifying y = -6.718578799Subproblem 2
y + 49.5 = -42.781421201 Simplifying y + 49.5 = -42.781421201 Reorder the terms: 49.5 + y = -42.781421201 Solving 49.5 + y = -42.781421201 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-49.5' to each side of the equation. 49.5 + -49.5 + y = -42.781421201 + -49.5 Combine like terms: 49.5 + -49.5 = 0.0 0.0 + y = -42.781421201 + -49.5 y = -42.781421201 + -49.5 Combine like terms: -42.781421201 + -49.5 = -92.281421201 y = -92.281421201 Simplifying y = -92.281421201Solution
