Simplifying 0 = x2 + -25x + 120 Reorder the terms: 0 = 120 + -25x + x2 Solving 0 = 120 + -25x + x2 Solving for variable 'x'. Combine like terms: 0 + -120 = -120 -120 + 25x + -1x2 = 120 + -25x + x2 + -120 + 25x + -1x2 Reorder the terms: -120 + 25x + -1x2 = 120 + -120 + -25x + 25x + x2 + -1x2 Combine like terms: 120 + -120 = 0 -120 + 25x + -1x2 = 0 + -25x + 25x + x2 + -1x2 -120 + 25x + -1x2 = -25x + 25x + x2 + -1x2 Combine like terms: -25x + 25x = 0 -120 + 25x + -1x2 = 0 + x2 + -1x2 -120 + 25x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -120 + 25x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 120 + -25x + x2 = 0 Move the constant term to the right: Add '-120' to each side of the equation. 120 + -25x + -120 + x2 = 0 + -120 Reorder the terms: 120 + -120 + -25x + x2 = 0 + -120 Combine like terms: 120 + -120 = 0 0 + -25x + x2 = 0 + -120 -25x + x2 = 0 + -120 Combine like terms: 0 + -120 = -120 -25x + x2 = -120 The x term is -25x. Take half its coefficient (-12.5). Square it (156.25) and add it to both sides. Add '156.25' to each side of the equation. -25x + 156.25 + x2 = -120 + 156.25 Reorder the terms: 156.25 + -25x + x2 = -120 + 156.25 Combine like terms: -120 + 156.25 = 36.25 156.25 + -25x + x2 = 36.25 Factor a perfect square on the left side: (x + -12.5)(x + -12.5) = 36.25 Calculate the square root of the right side: 6.020797289 Break this problem into two subproblems by setting (x + -12.5) equal to 6.020797289 and -6.020797289.Subproblem 1
x + -12.5 = 6.020797289 Simplifying x + -12.5 = 6.020797289 Reorder the terms: -12.5 + x = 6.020797289 Solving -12.5 + x = 6.020797289 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12.5' to each side of the equation. -12.5 + 12.5 + x = 6.020797289 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + x = 6.020797289 + 12.5 x = 6.020797289 + 12.5 Combine like terms: 6.020797289 + 12.5 = 18.520797289 x = 18.520797289 Simplifying x = 18.520797289Subproblem 2
x + -12.5 = -6.020797289 Simplifying x + -12.5 = -6.020797289 Reorder the terms: -12.5 + x = -6.020797289 Solving -12.5 + x = -6.020797289 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12.5' to each side of the equation. -12.5 + 12.5 + x = -6.020797289 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + x = -6.020797289 + 12.5 x = -6.020797289 + 12.5 Combine like terms: -6.020797289 + 12.5 = 6.479202711 x = 6.479202711 Simplifying x = 6.479202711Solution
