Simplifying y2 + -20y + 27 = 0 Reorder the terms: 27 + -20y + y2 = 0 Solving 27 + -20y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-27' to each side of the equation. 27 + -20y + -27 + y2 = 0 + -27 Reorder the terms: 27 + -27 + -20y + y2 = 0 + -27 Combine like terms: 27 + -27 = 0 0 + -20y + y2 = 0 + -27 -20y + y2 = 0 + -27 Combine like terms: 0 + -27 = -27 -20y + y2 = -27 The y term is -20y. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20y + 100 + y2 = -27 + 100 Reorder the terms: 100 + -20y + y2 = -27 + 100 Combine like terms: -27 + 100 = 73 100 + -20y + y2 = 73 Factor a perfect square on the left side: (y + -10)(y + -10) = 73 Calculate the square root of the right side: 8.544003745 Break this problem into two subproblems by setting (y + -10) equal to 8.544003745 and -8.544003745.Subproblem 1
y + -10 = 8.544003745 Simplifying y + -10 = 8.544003745 Reorder the terms: -10 + y = 8.544003745 Solving -10 + y = 8.544003745 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + y = 8.544003745 + 10 Combine like terms: -10 + 10 = 0 0 + y = 8.544003745 + 10 y = 8.544003745 + 10 Combine like terms: 8.544003745 + 10 = 18.544003745 y = 18.544003745 Simplifying y = 18.544003745Subproblem 2
