Simplifying y2 + -14y + -30 = 0 Reorder the terms: -30 + -14y + y2 = 0 Solving -30 + -14y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + -14y + 30 + y2 = 0 + 30 Reorder the terms: -30 + 30 + -14y + y2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + -14y + y2 = 0 + 30 -14y + y2 = 0 + 30 Combine like terms: 0 + 30 = 30 -14y + y2 = 30 The y term is -14y. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14y + 49 + y2 = 30 + 49 Reorder the terms: 49 + -14y + y2 = 30 + 49 Combine like terms: 30 + 49 = 79 49 + -14y + y2 = 79 Factor a perfect square on the left side: (y + -7)(y + -7) = 79 Calculate the square root of the right side: 8.888194417 Break this problem into two subproblems by setting (y + -7) equal to 8.888194417 and -8.888194417.Subproblem 1
y + -7 = 8.888194417 Simplifying y + -7 = 8.888194417 Reorder the terms: -7 + y = 8.888194417 Solving -7 + y = 8.888194417 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + y = 8.888194417 + 7 Combine like terms: -7 + 7 = 0 0 + y = 8.888194417 + 7 y = 8.888194417 + 7 Combine like terms: 8.888194417 + 7 = 15.888194417 y = 15.888194417 Simplifying y = 15.888194417Subproblem 2
y + -7 = -8.888194417 Simplifying y + -7 = -8.888194417 Reorder the terms: -7 + y = -8.888194417 Solving -7 + y = -8.888194417 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + y = -8.888194417 + 7 Combine like terms: -7 + 7 = 0 0 + y = -8.888194417 + 7 y = -8.888194417 + 7 Combine like terms: -8.888194417 + 7 = -1.888194417 y = -1.888194417 Simplifying y = -1.888194417Solution
